 When Anubis decides it needs to send a challenge to your browser, it sends a challenge page. Historically, this challenge page is [an HTML template](https://github.com/TecharoHQ/anubis/blob/main/web/index.templ) that kicks off some JavaScript, reads the challenge information out of the page body, and then solves it as fast as possible in order to let users see the website they want to visit.

+
+## Root cause analysis
+
+In simplify server management, Techaro runs a [Kubernetes](https://kubernetes.io/) cluster on [Vultr VKE](https://www.vultr.com/kubernetes/) (Vultr Kubernetes Engine). When you do this, Vultr needs to provision a [load balancer](https://docs.vultr.com/how-to-use-a-vultr-load-balancer-with-vke) to bridge the gap between the outside world and the Kubernetes world, kinda like this:
+
+```mermaid
+---
+title: Overall architecture
+---
+
+flowchart LR
+    UT(User Traffic)
+    subgraph Provider Infrastructure
+      LB[Load Balancer]
+    end
+    subgraph Kubernetes
+        IN(ingress-nginx)
+        TH(Thoth)
+        AN(Anubis Docs)
+        OS(Other sites)
+
+        IN --> TH
+        IN --> AN
+        IN --> OS
+    end
+
+    UT --> LB --> IN
+```
+
+Techaro controls everything inside the Kubernetes side of that diagram. Anything else is out of our control. That load balancer is routed to the public internet via [Border Gateway Protocol (BGP)](https://en.wikipedia.org/wiki/Border_Gateway_Protocol).
+
+If there is an interruption with the BGP sessions in the upstream provider, this can manifest as things either not working or inconsistently working. This is made more difficult by the fact that the IPv4 and IPv6 internets are technically separate networks. With this in mind, it's very possible to have IPv4 traffic fail but not IPv6 traffic.
+
+The root cause is that the hosting provider we use for production services had flapping IPv4 BGP sessions in its Toronto region. When this happens all we can do is open a ticket and wait for it to come back up.
+
+## Where we got lucky
+
+The Uptime Kuma instance that caught this incident runs on an IPv4-only network. If it was dual stack, this would not have been caught as quickly.
+
+The `ingress-nginx` logs print IP addresses of remote clients to the log feed. If this was not the case, it would be much more difficult to find this error.
+
+## Action items
+
+- A single instance of downtime like this is not enough reason to move providers. Moving providers because of this is thus out of scope.
+- Techaro needs a status page hosted on a different cloud provider than is used for the production cluster (`TecharoHQ/TODO#6`).
+- Health checks for IPv4 and IPv6 traffic need to be created (`TecharoHQ/TODO#7`).
+- Remove the requirement for [Anubis to pass Thoth health checks before it can start if Thoth is enabled](https://github.com/TecharoHQ/anubis/pull/794).

+
+Hey all!
+
+Recently we released [Anubis v1.21.1: Minfilia Warde (Echo 1)](https://github.com/TecharoHQ/anubis/releases/tag/v1.21.1). This is a fairly meaty release and like [last time](../2025-06-27-release-1.20.0/index.mdx) this blogpost will tell you what you need to know before you update. Kick back, get some popcorn and let's dig into this!
+
+{/* truncate */}
+
+In this release, Anubis becomes internationalized, gains the ability to use system load as input to issuing challenges, finally fixes the "invalid response" after "success" bug, and more! Please read these notes before upgrading as the changes are big enough that administrators should take action to ensure that the upgrade goes smoothly.
+
+This release is brought to you by [FreeCAD](https://www.freecad.org/), an open-source computer aided design tool that lets you design things for the real world.
+
+## What's in this release?
+
+The biggest change is that the ["invalid response" after "success" bug](https://github.com/TecharoHQ/anubis/issues/564) is now finally fixed for good by totally rewriting how [Anubis' challenge issuance flow works](#challenge-flow-v2).
+
+This release gives Anubis the following features:
+
+- [Internationalization support](#internationalization), allowing Anubis to render its messages in the human language you speak.
+- Anubis now supports the [`missingHeader`](#missingHeader-function) function to assert the absence of headers in requests.
+- Anubis now has the ability to [store data persistently on the server](#persistent-data-storage).
+- Anubis can use [the system load average](#load-average-checks) as a factor to determine if it needs to filter traffic or not.
+- Add `COOKIE_SECURE` option to set the cookie [Secure flag](https://developer.mozilla.org/en-US/docs/Web/HTTP/Guides/Cookies#block_access_to_your_cookies)
+- Sets cookie defaults to use [SameSite: None](https://web.dev/articles/samesite-cookies-explained)
+- Allow [Common Crawl](https://commoncrawl.org/) by default so scrapers have less incentive to scrape
+- Add `/healthz` metrics route for use in platform-based health checks.
+- Start exposing JA4H fingerprints for later use in CEL expressions.
+
+And this release also fixes the following bugs:
+
+- [Challenge issuance has been totally rewritten](#challenge-flow-v2) to finally squash the infamous ["invalid response" after "success" bug](https://github.com/TecharoHQ/anubis/issues/564) for good.
+- In order to reduce confusion, the "Success" interstitial that shows up when you pass a proof of work challenge has been removed.
+- Don't block Anubis starting up if [Thoth](/docs/admin/thoth/) health checks fail.
+- The "Try again" button on the error page has been fixed. Previously it meant "try the solution again" instead of "try the challenge again".
+- In certain cases, a user could be stuck with a test cookie that is invalid, locking them out of the service for up to half an hour. This has been fixed with better validation of this case and clearing the cookie.
+- "Proof of work" has been removed from the branding due to some users having extremely negative connotations with it.
+
+We try to avoid introducing breaking changes as much as possible, but these are the changes that may be relevant for you as an administrator:

+### Sponsoring the project
+
+If you rely on Anubis to keep your website safe, please consider sponsoring the project on [GitHub Sponsors](https://github.com/sponsors/Xe) or [Patreon](https://patreon.com/cadey). Funding helps pay hosting bills and offset the time spent on making this project the best it can be. Every little bit helps and when enough money is raised, [I can make Anubis my full-time job](https://github.com/TecharoHQ/anubis/discussions/278).
+
+Once this pie chart is at 100%, I can start to reduce my hours at my day job as most of my needs will be met (pre-tax):

+If facts or local regulations demand, you can set Anubis default language with the `FORCED_LANGUAGE` environment variable or the `--forced-language` command line argument:
+
+```sh
+FORCED_LANGUAGE=de
+```
+
+## Big ticket bug fixes
+
+These issues affect every user of Anubis. Administrators should upgrade Anubis as soon as possible to mitigate them.
+
+### Fix event loop thrashing when solving a proof of work challenge
+
+Anubis has a progress bar so that users can have something moving while it works. This gives users more confidence that something is happening and that the website is not being malicious with CPU usage. However, the way it was implemented way back in [#87](https://github.com/TecharoHQ/anubis/pull/87) had a subtle bug:
+
+```js
+if (
+  (nonce > oldNonce) | 1023 && // we've wrapped past 1024
+  (nonce >> 10) % threads === threadId // and it's our turn
+) {
+  postMessage(nonce);
+}
+```
+
+The logic here looks fine but is subtly wrong as was reported in [#877](https://github.com/TecharoHQ/anubis/issues/877) by the main Pale Moon developer.
+
+For context, `nonce` is a counter that increments by the worker count every loop. This is intended to spread the load between CPU cores as such:
+
+| Iteration | Worker ID | Nonce |
+| :-------- | :-------- | :---- |
+| 1         | 0         | 0     |
+| 1         | 1         | 1     |
+| 2         | 0         | 2     |
+| 2         | 1         | 3     |
+
+And so on. This makes the proof of work challenge as fast as it can possibly be so that Anubis quickly goes away and you can enjoy the service it is protecting.
+
+The incorrect part of this is the boolean logic, specifically the part with the bitwise or `|`. I think the intent was to use a logical or (`||`), but this had the effect of making the `postMessage` handler fire on every iteration. The intent of this snippet (as the comment clearly indicates) is to make sure that the main event loop is only updated with the worker status every 1024 iterations per worker. This had the opposite effect, causing a lot of messages to be sent from workers to the parent JavaScript context.
+
+This is bad for the event loop.
+
+Instead, I have ripped out that statement and replaced it with a much simpler increment only counter that fires every 1024 iterations. Additionally, only the first thread communicates back to the parent process. This does mean that in theory the other workers could be ahead of the first thread (posting a message out of a worker has a nonzero cost), but in practice I don't think this will be as much of an issue as the current behaviour is.
+
+The root cause of the stack exhaustion is likely the pressure caused by all of the postMessage futures piling up. Maybe the larger stack size in 64 bit environments is causing this to be fine there, maybe it's some combination of newer hardware in 64 bit systems making this not be as much of a problem due to it being able to handle events fast enough to keep up with the pressure.
+
+Either way, thanks much to [@wolfbeast](https://github.com/wolfbeast) and the Pale Moon community for finding this. This will make Anubis faster for everyone!
+
+### Fix potential memory leak when discovering a solution
+
+In some cases, the parallel solution finder in Anubis could cause all of the worker promises to leak due to the fact the promises were being improperly terminated. A recursion bomb happens in the following scenario:
+
+1. A worker sends a message indicating it found a solution to the proof of work challenge.
+2. The `onmessage` handler for that worker calls `terminate()`
+3. Inside `terminate()`, the parent process loops through all other workers and calls `w.terminate()` on them.
+4. It's possible that terminating a worker could lead to the `onerror` event handler.
+5. This would create a recursive loop of `onmessage` -> `terminate` -> `onerror` -> `terminate` -> `onerror` and so on.
+
+This infinite recursion quickly consumes all available stack space, but this has never been noticed in development because all of my computers have at least 64Gi of ram provisioned to them under the axiom paying for more ram is cheaper than paying in my time spent having to work around not having enough ram. Additionally, ia32 has a smaller base stack size, which means that they will run into this issue much sooner than users on other CPU architectures will.
+
+The fix adds a boolean `settled` flag to prevent termination from running more than once.
+
+## Expressions features
+
+Anubis v1.21.1 adds additional [expressions](/docs/admin/configuration/expressions) features so that you can make your request matching even more granular.
+
+### `missingHeader` function
+
+Anubis [expressions](/docs/admin/configuration/expressions) have [a few functions exposed](/docs/admin/configuration/expressions/#functions-exposed-to-anubis-expressions). Anubis v1.21.1 adds the `missingHeader` function, allowing you to assert the _absence_ of a header in requests.
+
+Let's say you're getting a lot of requests from clients that are pretending to be Google Chrome. Google Chrome sends a few signals to web servers, the main one of them is the [`Sec-Ch-Ua`](https://developer.mozilla.org/en-US/docs/Web/HTTP/Reference/Headers/Sec-CH-UA). Sec-CH-UA is part of Google's [User Agent Client Hints](https://wicg.github.io/ua-client-hints/#sec-ch-ua) proposal, but it being present is a sign that the client is more likely Google Chrome than not. With the `missingHeader` function, you can write a rule to [add weight](/docs/admin/policies/#request-weight) to requests without `Sec-Ch-Ua` that claim to be Google Chrome.
+
+```yaml
+# Adds weight clients that claim to be Google Chrome without setting Sec-Ch-Ua
+- name: old-chrome
+  action: WEIGH
+  weight:
+    adjust: 10
+  expression:
+    all:
+      - userAgent.matches("Chrome/[1-9][0-9]?\\.0\\.0\\.0")
+      - missingHeader(headers, "Sec-Ch-Ua")
+```
+
+When combined with [weight thresholds](/docs/admin/configuration/thresholds), this allows you to make requests that don't match the signature of Google Chrome more suspicious, which will make them have a more difficult challenge.
+
+### Load average checks
+
+Anubis can dynamically take action [based on the system load average](/docs/admin/configuration/expressions/#using-the-system-load-average), allowing you to write rules like this:
+
+```yaml
+## System load based checks.
+# If the system is under high load for the last minute, add weight.
+- name: high-load-average
+  action: WEIGH
+  expression: load_1m >= 10.0 # make sure to end the load comparison in a .0
+  weight:
+    adjust: 20
+
+# If it is not for the last 15 minutes, remove weight.
+- name: low-load-average
+  action: WEIGH
+  expression: load_15m <= 4.0 # make sure to end the load comparison in a .0
+  weight:
+    adjust: -10
+```
+
+Something to keep in mind about system load average is that it is not aware of the number of cores the system has. If you have a 16 core system that has 16 processes running but none of them is hogging the CPU, then you will get a load average below 16. If you are in doubt, make your "high load" metric at least two times the number of CPU cores and your "low load" metric at least half of the number of CPU cores. For example:
+
+|      Kind | Core count | Load threshold |
+| --------: | :--------- | :------------- |
+| high load | 4          | `8.0`          |
+|  low load | 4          | `2.0`          |
+| high load | 16         | `32.0`         |
+|  low load | 16         | `8`            |
+
+Also keep in mind that this does not account for other kinds of latency like I/O latency or downstream API response latency. A system can have its web applications unresponsive due to high latency from a MySQL server but still have that web application server report a load near or at zero.
+
+:::note
+
+This does not work if you are using Kubernetes.
+
+:::
+
+When combined with [weight thresholds](/docs/admin/configuration/thresholds), this allows you to make incoming sessions "back off" while the server is under high load.
+
+## Challenge flow v2
+
+The main goal of Anubis is to weigh the risks of incoming requests in order to protect upstream resources against abusive clients like badly written scrapers. In order to separate "good" clients (like users wanting to learn from a website's content) from "bad" clients, Anubis issues [challenges](/docs/admin/configuration/challenges/).
+
+Previously the Anubis challenge flow looked like this:
+
+```mermaid
+---
+title: Old Anubis challenge flow
+---
+flowchart LR
+    user(User Browser)
+    subgraph Anubis
+        mIC{Challenge?}
+        ic(Issue Challenge)
+        rp(Proxy to service)
+        mIC -->|User needs a challenge| ic
+        mIC -->|User does not need a challenge| rp
+    end
+    target(Target Service)
+    rp --> target
+    user --> mIC
+    ic -->|Pass a challenge| user
+    target -->|Site data| users
+```
+
+In order to issue a challenge, Anubis generated a challenge string based on request metadata that we assumed wouldn't drastically change between requests, including but not limited to:
+
+- The client's User-Agent string.
+- The client [`Accept-Language` header](https://developer.mozilla.org/en-US/docs/Web/HTTP/Reference/Headers/Accept-Language) value.
+- The client's IP address.
+
+Anubis also didn't store any information about challenges so that it can remain lightweight and handle the onslaught of requests from scrapers. The assumption was that the challenge string function was idempotent per client across time. What actually ended up happening was something like this:
+
+```mermaid
+---
+title: Anubis challenge string idempotency
+---
+sequenceDiagram
+    User->>+Anubis: GET /wiki/some-page
+    Anubis->>+Make Challenge: Generate a challenge string
+    Make Challenge->>-Anubis: Challenge string: taco salad
+    Anubis->>-User: HTTP 401 solve a challenge
+    User->>+Anubis: GET internal-api/pass-challenge
+    Anubis->>+Make Challenge: Generate a challenge string
+    Make Challenge->>-Anubis: Challenge string: burrito bar
+    Anubis->>+User: Error: invalid response
+```
+
+Various attempts were made to fix this. All of these ended up failing. Many difficulties were discovered including but not limited to:
+
+- Removing `Accept-Language` from consideration because [Chrome randomizes the contents of `Accept-Language` to reduce fingerprinting](https://github.com/explainers-by-googlers/reduce-accept-language), a behaviour which [causes a lot of confusion](https://www.reddit.com/r/chrome/comments/nhpnez/google_chrome_is_randomly_switching_languages_on/) for users with multiple system languages selected.
+- [IPv6 privacy extensions](https://www.internetsociety.org/resources/deploy360/2014/privacy-extensions-for-ipv6-slaac/) mean that each request could be coming from a different IP address (at least one legitimate user in the wild has been observed to have a different IP address per TCP session across an entire `/48`).
+- Some [US mobile phone carriers make it too easy for your IP address to drastically change](https://news.ycombinator.com/item?id=32038215) without user input.
+- [Happy eyeballs](https://en.wikipedia.org/wiki/Happy_Eyeballs) means that some requests can come in over IPv4 and some requests can come in over IPv6.
+- To make things worse, you can't even assert that users are from the same [BGP autonomous system](<https://en.wikipedia.org/wiki/Autonomous_system_(Internet)>) because some users could have ISPs that are IPv4 only, forcing them to use a different IP address space to get IPv6 internet access. This sounds like it's rare enough, but I personally have to do this even though I pay for 8 gigabit fiber from my ISP and only get IPv4 service from them.
+
+Amusingly enough, the only part of this that has survived is the assertion that a user hasn't changed their `User-Agent` string. Maybe [that one guy that sets his Chrome version to `150`](https://github.com/TecharoHQ/anubis/issues/239) would have issues, but so far I've not seen any evidence that a client randomly changing their user agent between challenge issuance and solving can possibly be legitimate.
+
+As a result, the entire subsystem that generated challenges before had to be ripped out and rewritten from scratch.
+
+It was replaced with a new flow that stores data on the server side, compares that data against what the client responds with, and then checks pass/fail that way:
+
+```mermaid
+---
+title: New challenge flow
+---
+sequenceDiagram
+    User->>+Anubis: GET /wiki/some-page
+    Anubis->>+Make Challenge: Generate a challenge string
+    Make Challenge->>+Store: Store info for challenge 1234
+    Make Challenge->>-Anubis: Challenge string: taco salad, ID 1234
+    Anubis->>-User: HTTP 401 solve a challenge
+    User->>+Anubis: GET internal-api/pass-challenge, challenge 1234
+    Anubis->>+Validate Challenge: verify challenge 1234
+    Validate Challenge->>+Store: Get info for challenge 1234
+    Store->>-Validate Challenge: Here you go!
+    Validate Challenge->>-Anubis: Valid ✅
+    Anubis->>+User: Here's a cookie to get past Anubis
+```
+
+As a result, the [challenge format](#challenge-format-change) had to change. Old cookies will still be validated, but the next minor version (v1.22.0) will include validation to ensure that all challenges are accounted for on the server side. This data is stored in the active [storage backend](/docs/admin/policies/#storage-backends) for up to 30 minutes. This also fixes [#746](https://github.com/TecharoHQ/anubis/issues/746) and other similar instances of this issue.
+
+### Challenge format change
+
+Previously Anubis did no accounting for challenges that it issued. This means that if Anubis restarted during a client, the client would be able to proceed once Anubis came back online.
+
+During the upgrade to v1.21.0 and when v1.21.0 (or later) restarts with the [in-memory storage backend](/docs/admin/policies/#memory), you may see a higher rate of failed challenges than normal. If this persists beyond a few minutes, [open an issue](https://github.com/TecharoHQ/anubis/issues/new).
+
+If you are using the in-memory storage backend, please consider using [a different storage backend](/docs/admin/policies/#storage-backends).
+
+### Storage
+
+Anubis offers a few different storage backends depending on your needs:
+
+| Backend                                  | Description                                                                                                    |
+| :--------------------------------------- | :------------------------------------------------------------------------------------------------------------- |
+| [`memory`](/docs/admin/policies/#memory) | An in-memory hashmap that is cleared when Anubis is restarted.                                                 |
+| [`bbolt`](/docs/admin/policies/#bbolt)   | A memory-mapped key/value store that can persist between Anubis restarts.                                      |
+| [`valkey`](/docs/admin/policies/#valkey) | A networked key/value store that can persist between Anubis restarts and coordinate across multiple instances. |
+
+Please review the documentation for each storage method to figure out the one best for your needs. If you aren't sure, consult this diagram:
+
+```mermaid
+---
+title: What storage backend do I need?
+---
+flowchart TD
+    OneInstance{Do you only have
+one instance of
+Anubis?}
+    Persistence{Do you have
+persistent disk
+access in your
+environment?}
+    bbolt[(bbolt)]
+    memory[(memory)]
+    valkey[(valkey)]
+    OneInstance -->|Yes| Persistence
+    OneInstance -->|No| valkey
+    Persistence -->|Yes| bbolt
+    Persistence -->|No| memory
+```
+
+## Breaking change: systemd `RuntimeDirectory` change
+
+The following potentially breaking change applies to native installs with systemd only:
+
+Each instance of systemd service template now has a unique `RuntimeDirectory`, as opposed to each instance of the service sharing a `RuntimeDirectory`. This change was made to avoid [the `RuntimeDirectory` getting nuked](https://github.com/TecharoHQ/anubis/issues/748) any time one of the Anubis instances restarts.
+
+If you configured Anubis' unix sockets to listen on `/run/anubis/foo.sock` for instance `anubis@foo`, you will need to configure Anubis to listen on `/run/anubis/foo/foo.sock` and additionally configure your HTTP load balancer as appropriate.
+
+If you need the legacy behaviour, install this [systemd unit dropin](https://www.flatcar.org/docs/latest/setup/systemd/drop-in-units/):
+
+```systemd
+# /etc/systemd/system/anubis@.service.d/50-runtimedir.conf
+[Service]
+RuntimeDirectory=anubis
+```
+
+Just keep in mind that this will cause problems when Anubis restarts.
+
+## What's up next?
+
+The biggest things we want to do in the next release (in no particular order):
+
+- A rewrite of bot checking rule configuration syntax to make it less ambiguous.
+- [JA4](https://blog.foxio.io/ja4+-network-fingerprinting) (and other forms of) fingerprinting and coordination with [Thoth](/docs/admin/thoth/) to allow clients with high aggregate pass rates through without seeing Anubis at all.
+- Advanced heuristics for [users of the unbranded variant of Anubis](/docs/admin/botstopper/).
+- Optimize the release flow so that releases can be triggered and executed by continuous integration tools. The ultimate goal is to make it possible to release Anubis in 15 minutes after pressing a single "mint release" button.
+- Add "hot reloading" support to Anubis, allowing administrators to update the rules without restarting the service.
+- Fix [multiple slash support](https://github.com/TecharoHQ/anubis/issues/754) for web applications that require optional path variables.
+- Add weight to "brand new" clients.
+- Implement a "maze" feature that tries to get crawlers ensnared in a maze of random links so that clients that are more than 20 links in can be reported to the home base.
+- Open [Thoth-based advanced checks](/docs/admin/thoth/) to more users with an easier onboarding flow.
+- More smoke tests including for browsers like [Pale Moon](https://www.palemoon.org/).

+
+As we finish up work on [all of the features in the next release of Anubis](/docs/CHANGELOG#unreleased), I took a moment to add up the financials and here's an update on the recurring revenue of the project. Once I reach the [$5000 per month](https://github.com/TecharoHQ/anubis/discussions/278) mark, I can start reducing hours at my dayjob and start to make working on Anubis my full time job.
+
+{/* truncate */}
+
+Note that this only counts _recurring_ revenue (subscriptions to [BotStopper](/docs/admin/botstopper) and monthly repeating donations). Every one of the one-time donations I get is a gift and I am grateful for them, but I cannot make critically important financial decisions off of sporadic one-time donations.
+
+:::note
+
+All currency figures in this article are USD (United States Dollars) unless denoted otherwise.
+
+:::
+
+Here's the funding breakdown by income stream:
+
+```mermaid
+pie title Funding update August 2025
+    "GitHub Sponsors" : 3500
+    "Patreon" : 1500
+    "Liberapay" : 100
+    "Remaining" : 4800
+```
+
+Assuming that some of my private support contracts and other sales effort go through, this will slightly change the shapes of this (a new pie chart segment will emerge for "Manual invoices"), but I am halfway there. This is a huge bar to pass and as it stands right now this is just enough income to pay for my monthly rent (not accounting for tax).
+
+As a reminder, here's the rough plan for the phases I want to hit based on the _recurring_ donation totals:
+
+| Monthly donations           | Details                                                                                                                                                                     |

+| $5,000-10,000 per month     | Anubis gets 1-2 days per week of my time put into it consistently and I go part-time at my dayjob.                                                                          |
+| $10,000-15,000 per month    | Anubis becomes my full time job. Features that are currently exclusive to [BotStopper](/docs/admin/botstopper/) start to trickle down to the open source version of Anubis. |
+| $15,000 per month and above | I start planning hiring for Techaro.                                                                                                                                        |
+
+If your organization benefits from Anubis, please consider donating to the project in order to make this sustainable. The fewer financial problems I have means the more that Anubis can become better.
+
+## New funding platform: Liberapay
+
+After many comments about the funding options, I have set up [Liberapay](https://liberapay.com/Xe/) as an option to receive donations. Additional funding targets will be added to Liberapay as soon as I hear back from my accountant with more information. All money received via Liberapay goes directly towards supporting the project.
+
+## Next goals
+
+Here's my short term goals for the immediate future:
+
+1. Finish [Thoth](/docs/admin/thoth/) and run a backfill to mass issue API keys.
+2. Document and publish the writeup for the multi-region Google Cloud spot instance setup that Thoth is built upon.
+3. Release v1.22.0 of Anubis with Traefik support and other important fixes.
+4. Continue growing the project into a sustainable business.
+5. Work through the [blog backlog](https://github.com/TecharoHQ/anubis/issues?q=is%3Aissue%20state%3Aopen%20label%3Ablog) to document the thoughts behind Anubis and how parts of it work.
+
+Thank you for supporting Anubis! It's only going to get better from here.

+
+One of the biggest lessons that I've learned in my career is that all software has bugs, and the more complicated your software gets the more complicated your bugs get. A lot of the time those bugs will be fairly obvious and easy to spot, validate, and replicate. Sometimes, the process of fixing it will uncover your core assumptions about how things work in ways that will leave you feeling like you just got trolled.
+
+Today I'm going to talk about a single line fix that prevents people on a large number of devices from having weird irreproducible issues with Anubis rejecting people when it frankly shouldn't. Stick around, it's gonna be a wild ride.
+
+{/* truncate */}
+
+## How this happened
+
+Anubis is a web application firewall that tries to make sure that the client is a browser. It uses a few [challenge methods](/docs/admin/configuration/challenges/) to do this determination, but the main method is the [proof of work](/docs/admin/configuration/challenges/proof-of-work/) challenge which makes clients grind away at cryptographic checksums in order to rate limit clients from connecting too eagerly.
+
+:::note
+
+In retrospect implementing the proof of work challenge may have been a mistake and it's likely to be supplanted by things like [Proof of React](https://github.com/TecharoHQ/anubis/pull/1038) or other methods that have yet to be developed. Your patience and polite behaviour in the bug tracker is appreciated.
+
+:::
+
+In order to make sure the proof of work challenge screen _goes away as fast as possible_, the [worker code](https://github.com/TecharoHQ/anubis/tree/main/web/js/worker) is optimized within an inch of its digital life. One of the main ways that this code is optimized is with how it's run. Over the last 10-20 years, the main way that CPUs have gotten fast is via increasing multicore performance. Anubis tries to make sure that it can use as many cores as possible in order to take advantage of your device's CPU as much as it can.
+
+This strategy sometimes has some issues though, for one Firefox seems to get _much slower_ if you have Anubis try to absolutely saturate all of the cores on the system. It also has a fairly high overhead between JavaScript JIT code and [WebCrypto](https://developer.mozilla.org/en-US/docs/Web/API/Web_Crypto_API). I did some testing and found out that Firefox's point of diminishing returns was about half of the CPU cores.
+
+## Another "invalid response" bug
+
+One of the complaints I've been getting from users and administrators using Anubis is that they've been running into issues where users get randomly rejected with an error message only saying "invalid response". This happens when the challenge validating process fails. This issue has been blocking the release of the next version of Anubis.
+
+In order to demonstrate this better, I've made a little interactive diagram for the proof of work process:
+
+<ProofOfWorkDiagram />
+
+I've fixed a lot of the easy bugs in Anubis by this point. A lot of what's left is the hard bugs, but also specifically the kinds of hard bugs that involve weird hardware configurations. In order to try and catch these issues before software hits prod, I test Anubis against a bunch of hardware I have locally. Any issues I find and fix before software ships are issues that you don't hit in production.
+
+Let's consider [the line of code](https://github.com/TecharoHQ/anubis/blob/main/web/js/algorithms/fast.mjs) that was causing this issue:
+
+```js
+threads = Math.max(navigator.hardwareConcurrency / 2, 1),
+```
+
+This is intended to make your browser spawn a proof of work worker for _half_ of your available CPU cores. If you only have one CPU core, you should only have one worker. Each thread is given this number of threads and uses that to increment the nonce so that each thread doesn't try to find a solution that another worker has already performed.
+
+One of the subtle problems here is that all of the parts of this assume that the thread ID and nonce are integers without a decimal portion. Famously, [all JavaScript numbers are IEEE 754 floating point numbers](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Number). Surely there wouldn't be a case where the thread count could be a _decimal_ number, right?
+
+Here's all the devices I use to test Anubis _and their core counts_:
+
+| Device Name                  | Core Count |
+| :--------------------------- | :--------- |
+| MacBook Pro M3 Max           | 16         |
+| MacBook Pro M4 Max           | 16         |
+| AMD Ryzen 9 7950x3D          | 32         |
+| Google Pixel 9a (GrapheneOS) | 8          |
+| iPhone 15 Pro Max            | 6          |
+| iPad Pro (M1)                | 8          |
+| iPad mini                    | 6          |
+| Steam Deck                   | 8          |
+| Core i5 10600 (homelab)      | 12         |
+| ROG Ally                     | 16         |
+
+Notice something? All of those devices have an _even_ number of cores. Some devices such as the [Pixel 8 Pro](https://www.gsmarena.com/google_pixel_8_pro-12545.php) have an _odd_ number of cores. So what happens with that line of code as the JavaScript engine evaluates it?
+
+Let's replace the [`navigator.hardwareConcurrency`](https://developer.mozilla.org/en-US/docs/Web/API/Navigator/hardwareConcurrency) with the Pixel 8 Pro's 9 cores:
+
+```js
+threads = Math.max(9 / 2, 1),
+```
+
+Then divide it by two:
+
+```js
+threads = Math.max(4.5, 1),
+```
+
+Oops, that's not ideal. However `4.5` is bigger than `1`, so [`Math.max`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Math/max) returns that:
+
+```js
+threads = 4.5,
+```
+
+This means that each time the proof of work equation is calculated, there is a 50% chance that a valid solution would include a nonce with a decimal portion in it. If the client finds a solution with such a nonce, then it would think the client was successful and submit the solution to the server, but the server only expects whole numbers back so it rejects that as an invalid response.
+
+I keep telling more junior people that when you have the weirdest, most inconsistent bugs in software that it's going to boil down to the dumbest possible thing you can possibly imagine. People don't believe me, then they encounter bugs like this. Then they suddenly believe me.
+
+Here is the fix:
+
+```js
+threads = Math.trunc(Math.max(navigator.hardwareConcurrency / 2, 1)),
+```
+
+This uses [`Math.trunc`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Math/trunc) to truncate away the decimal portion so that the Pixel 8 Pro has `4` workers instead of `4.5` workers.
+
+## Today I learned this was possible
+
+This was a total "today I learned" moment. I didn't actually think that hardware vendors shipped processors with an odd number of cores, however if you look at the core geometry of the Pixel 8 Pro, it has _three_ tiers of processor cores:
+
+| Core type          | Core model           | Number |
+| :----------------- | :------------------- | :----- |
+| High performance   | 3 Ghz Cortex X3      | 1      |
+| Medium performance | 2.45 Ghz Cortex A715 | 4      |
+| High efficiency    | 2.15 Cortex A510     | 4      |
+| Total              |                      | 9      |
+
+I guess every assumption that developers have about CPU design is probably wrong.
+
+This probably isn't helped by the fact that for most of my career, the core count in phones has been largely irrelevant and most of the desktop / laptop CPUs I've had (where core count does matter) uses [simultaneous multithreading](https://en.wikipedia.org/wiki/Simultaneous_multithreading) to "multiply" the core count by two.
+
+The client side fix is a bit of an "emergency stop" button to try and mitigate the badness as early as possible. In general I'm quite aware of the terrible UX involved with this flow failing and I'm still noodling through ways to make that UX better and easier for users / administrators to debug.
+
+I'm looking into the following:
+
+1. This could have been prevented on the server side by doing less strict input validation in compliance with [Postel's Law](https://en.wikipedia.org/wiki/Robustness_principle). I feel nervous about making such a security-sensitive endpoint _more liberal_ with the inputs it can accept, but it may be fine? I need to consult with a security expert.
+2. Showing an encrypted error message on the "invalid response" page so that the user and administrator can work together to fix or report the issue. I remember Google doing this at least once, but I can't recall where I've seen it in the past. Either way, this is probably the most robust method even though it would require developing some additional tooling. I think it would be worth it.
+
+I'm likely going to go with the second option. I will need to figure out a good flow for this. It's likely going to involve [age](https://github.com/FiloSottile/age). I'll say more about this when I have more to say.
+
+In the meantime though, looks like I need to expense a used Pixel 8 Pro to add to the testing jungle for Anubis. If anyone has a deal out there, please let me know!
+
+Thank you to the people that have been polite and helpful when trying to root cause and fix this issue.

+title: Taking steps to end abusive traffic from cloud providers
+description: "Learn how to effectively file abuse reports with cloud providers to stop malicious traffic at its source and protect your services from automated abuse."
+authors: [xe]
+tags: [abuse, cloud, security, networking]

+
+![A peaceful goose pond](./goose-pond.webp)
+
+As part of Anubis's ongoing development, I've been working to reduce friction for legitimate users by minimizing unnecessary challenge pages. While this improves the user experience, it can potentially expose services to increased abuse from public cloud infrastructure. To help administrators better protect their services, I want to share my strategies for filing abuse reports with IP space owners, enabling us to address malicious scraping at its source.
+
+{/* truncate */}
+
+In general, there are two kinds of IP addresses:
+
+- Residential IP addresses: IP addresses that are allocated to residential customers such as home internet connections and cellular data plans. These IP addresses are increasingly shared between customers due to technologies like [CGNAT](https://en.wikipedia.org/wiki/Carrier-grade_NAT).
+- Commercial IP addresses: IP addresses that are allocated to commercial customers such as cloud providers, VPS providers, root server providers, and other such business to business companies. These IP addresses are almost always statically allocated to one customer for a very long period of time (typically the lifetime of the server unless they are using things like dedicated IP addresses).
+
+In general, filing abuse reports to residential IP addresses is a waste of time. The administrators do appreciate knowing what kinds of abusive traffic is causing grief, but many times the users of those IP addresses don't know that their computer is sending abusive traffic to your services. A lot of malware botnets that used to be used with DDOS for hire services are now being used as residential proxies. Those "free VPN apps" are almost certainly making you pay for your usage by making your computer a zombie in a botnet. At some level I really respect the hustle as they manage to sell other people's bandwidth for rates as ludicrous as $1.00 per gigabyte ingressed and egressed.
+
+:::note
+
+Keep in mind, I'm talking about the things you can find by searching "free VPN", not infrastructure for the public good like the Tor browser or I2P.
+
+:::
+
+What you should really focus on is traffic from commercial IP addresses, such as cloud providers. That's a case where the cloud customer is in direct violation of the acceptable use policy of the provider. Filing abuse reports gets the abuse team of the cloud provider to reach out to that customer and demand corrective action under threat of contractual violence.
+
+## How to make an abuse report
+
+In general, the best abuse reports contain the following information:
+
+- Time of abusive requests.
+- IP address, User-Agent header, or other unique identifiers that can help the abuse team educate the customer about their misbehaving infrastructure.
+- Does the abusive IP address request robots.txt? If not, be sure to include that information.
+- A brief description of the impact to your system such as high system load, pages not rendering, or database system crashes. This helps the provider establish the fact that their customer is causing you measurable harm.
+- Context as to what your service is, what it does, and why they should care.
+
+For example, let's say that someone was giving the Anubis docs a series of requests that caused the server to fall over and experience extended downtime. Here's what I would write to the abuse contact:
+
+> Hello,
+>
+> I have received abusive traffic from one of your customers that has resulted in a denial of service to the users of the Anubis documentation website. Anubis is a web application firewall that administrators use to protect their websites against mass scraping and this documentation website helps administrators get started.
+>
+> On or about Thursday, October 30th at 04:00 UTC, A flurry of requests from the IP range `127.34.0.0/24` started to hit the `/admin/` routes, which caused unreasonable database load and ended up crashing PostgreSQL. This caused the documentation website to go down for three hours as it happened while the administrators were asleep. Based on logs, this caused 353 distinct users to not be able to load the documentation and the users filed bugs about it.
+>
+> I have attached the HTTP frontend logs for the abusive requests from your IP range. To protect our systems in the meantime while we perform additional hardening, I have blocked that IP address range in both our IP firewall and web application firewall configuration. Based on these logs, your customer seems to not have requested the standard `robots.txt` file, which includes instructions to deny access to those routes.
+>
+> Please let me know what other information you need on your end.
+>
+> Sincerely,
+>
+> [normal email signature]
+
+Then in order to figure out where to send it, look the IP addresses up in the `whois` database. For example, if you want to find the abuse contact for the IP address `1.1.1.1`, use the [whois command](https://packages.debian.org/sid/whois) to find the abuse contact:
+
+```
+$ whois 1.1.1.1 | grep -i abuse
+% Abuse contact for '1.1.1.0 - 1.1.1.255' is 'helpdesk@apnic.net'
+abuse-c:        AA1412-AP
+remarks:        All Cloudflare abuse reporting can be done via
+remarks:        resolver-abuse@cloudflare.com
+abuse-mailbox:  helpdesk@apnic.net
+role:           ABUSE APNICRANDNETAU
+abuse-mailbox:  helpdesk@apnic.net
+mnt-by:         APNIC-ABUSE
+```
+
+The abuse contact will be named either `abuse-c` or `abuse-mailbox`. For greatest effect, I suggest including all listed email addresses in your email to the abuse contact.
+
+Once you send your email, you should expect a response within 2 business days at most. If they don't get back to you, please feel free to [contact me](https://xeiaso.net/contact/) so that the default set of Anubis rules can be edited according to patterns I'm seeing across the ecosystem.
+
+Just remember that many cloud providers do not know how bad the scraping problem is. Filing abuse complaints makes it their problem. They don't want it to be their problem.

 ## [Unreleased]

+- Add Polish locale ([#1292](https://github.com/TecharoHQ/anubis/pull/1309))
+
 <!-- This changes the project to: -->

+## v1.24.0: Y'shtola Rhul
+
+Anubis is back and better than ever! Lots of minor fixes with some big ones interspersed.
+
+- Fix panic when validating challenges after privacy-mode browsers strip headers and the follow-up request matches an `ALLOW` threshold.
+- Expose WEIGHT rule matches as Prometheus metrics.
+- Allow more OCI registry clients [based on feedback](https://github.com/TecharoHQ/anubis/pull/1253#issuecomment-3506744184).
+- Expose services directory in the embedded `(data)` filesystem.
+- Add Ukrainian locale ([#1044](https://github.com/TecharoHQ/anubis/pull/1044)).
+- Allow Renovate as an OCI registry client.
+- Properly handle 4in6 addresses so that IP matching works with those addresses.
+- Add support to simple Valkey/Redis cluster mode
+- Open Graph passthrough now reuses the configured target Host/SNI/TLS settings, so metadata fetches succeed when the upstream certificate differs from the public domain. ([1283](https://github.com/TecharoHQ/anubis/pull/1283))
+- Stabilize the CVE-2025-24369 regression test by always submitting an invalid proof instead of relying on random POW failures.
+- Refine the check that ensures the presence of the Accept header to avoid breaking docker clients.
+- Removed rules intended to reward actual browsers due to abuse in the wild.
+
+### Dataset poisoning
+
+Anubis has the ability to engage in [dataset poisoning attacks](https://www.anthropic.com/research/small-samples-poison) using the [dataset poisoning subsystem](./admin/honeypot/overview.mdx). This allows every Anubis instance to be a honeypot to attract and flag abusive scrapers so that no administrator action is required to ban them.
+
+There is much more information about this feature in [the dataset poisoning subsystem documentation](./admin/honeypot/overview.mdx). Administrators that are interested in learning how this feature works should consult that documentation.
+
+### Deprecate `report_as` in challenge configuration
+
+Previously Anubis let you lie to users about the difficulty of a challenge to interfere with operators of malicious scrapers as a psychological attack:
+
+```yaml
+bots:
+  # Punish any bot with "bot" in the user-agent string
+  # This is known to have a high false-positive rate, use at your own risk
+  - name: generic-bot-catchall
+    user_agent_regex: (?i:bot|crawler)
+    action: CHALLENGE
+    challenge:
+      difficulty: 16 # impossible
+      report_as: 4 # lie to the operator
+      algorithm: slow # intentionally waste CPU cycles and time
+```
+
+This has turned out to be a bad idea because it has caused massive user experience problems and has been removed. If you are using this setting, you will get a warning in your logs like this:
+
+```json
+{
+  "time": "2025-11-25T23:10:31.092201549-05:00",
+  "level": "WARN",
+  "source": {
+    "function": "github.com/TecharoHQ/anubis/lib/policy.ParseConfig",
+    "file": "/home/xe/code/TecharoHQ/anubis/lib/policy/policy.go",
+    "line": 201
+  },
+  "msg": "use of deprecated report_as setting detected, please remove this from your policy file when possible",
+  "at": "config-validate",
+  "name": "mild-suspicion"
+}
+```
+
+To remove this warning, remove this setting from your policy file.
+
+### Logging customization
+
+Anubis now supports the ability to log to multiple backends ("sinks"). This allows you to have Anubis [log to a file](./admin/policies.mdx#file-sink) instead of just logging to standard out. You can also customize the [logging level](./admin/policies.mdx#log-levels) in the policy file:
+
+```yaml
+logging:
+  level: "warn" # much less verbose logging
+  sink: file # log to a file
+  parameters:
+    file: "./var/anubis.log"
+    maxBackups: 3 # keep at least 3 old copies
+    maxBytes: 67108864 # each file can have up to 64 Mi of logs
+    maxAge: 7 # rotate files out every n days
+    oldFileTimeFormat: 2006-01-02T15-04-05 # RFC 3339-ish
+    compress: true # gzip-compress old log files
+    useLocalTime: false # timezone for rotated files is UTC
+```
+
+Additionally, information about [how Anubis uses each logging level](./admin/policies.mdx#log-levels) has been added to the documentation.
+
+### DNS Features
+
+- CEL expressions for:
+  - FCrDNS checks
+  - Forward DNS queries
+  - Reverse DNS queries
+  - `arpaReverseIP` to transform IPv4/6 addresses into ARPA reverse IP notation.
+  - `regexSafe` to escape regex special characters (useful for including `remoteAddress` or headers in regular expressions).
+- DNS cache and other optimizations to minimize unnecessary DNS queries.
+
+The DNS cache TTL can be changed in the bots config like this:
+
+```yaml
+dns_ttl:
+  forward: 600
+  reverse: 600
+```
+
+The default value for both forward and reverse queries is 300 seconds.
+
+The `verifyFCrDNS` CEL function has two overloads:
+
+- `(addr)`
+  Simply verifies that the remote side has PTR records pointing to the target address.
+- `(addr, ptrPattern)`
+  Verifies that the remote side refers to a specific domain and that this domain points to the target IP.
+
+## v1.23.1: Lyse Hext - Echo 1
+
+- Fix `SERVE_ROBOTS_TXT` setting after the double slash fix broke it.
+
+### Potentially breaking changes
+
+#### Remove default Tencent Cloud block rule
+
+v1.23.0 added a default rule to block Tencent Cloud. After an email from their abuse team where they promised to take action to clean up their reputation, I have removed the default block rule. If this network causes you problems, please contact [abuse@tencent.com](mailto:abuse@tencent.com) and supply the following information:
+
+- Time of abusive requests.
+- IP address, User-Agent header, or other unique identifiers that can help the abuse team educate the customer about their misbehaving infrastructure.
+- Does the abusive IP address request robots.txt? If not, be sure to include that information.
+- A brief description of the impact to your system such as high system load, pages not rendering, or database system crashes. This helps the provider establish the fact that their customer is causing you measurable harm.
+- Context as to what your service is, what it does, and why they should care.
+
+Mention that you are using Anubis or BotStopper to protect your services. If they do not respond to you, please [contact me](https://xeiaso.net/contact) as soon as possible.
+
+#### Docker / OCI registry clients
+
+Anubis v1.23.0 accidentally blocked Docker / OCI registry clients. In order to explicitly allow them, add an import for `(data)/clients/docker-client.yaml`:
+
+```yaml
+bots:
+  - import: (data)/meta/default-config.yaml
+  - import: (data)/clients/docker-client.yaml
+```
+
+This is technically a regression as these clients used to work in Anubis v1.22.0, however it is allowable to make this opt-in as most websites do not expect to be serving Docker / OCI registry client traffic.
+
+## v1.23.0: Lyse Hext
+
+- Add default tencent cloud DENY rule.
+- Added `(data)/meta/default-config.yaml` for importing the entire default configuration at once.
+- Add `-custom-real-ip-header` flag to get the original request IP from a different header than `x-real-ip`.
+- Add `contentLength` variable to bot expressions.
+- Add `COOKIE_SAME_SITE_MODE` to force anubis cookies SameSite value, and downgrade automatically from `None` to `Lax` if cookie is insecure.
+- Fix lock convoy problem in decaymap ([#1103](https://github.com/TecharoHQ/anubis/issues/1103)).
+- Fix lock convoy problem in bbolt by implementing the actor pattern ([#1103](https://github.com/TecharoHQ/anubis/issues/1103)).
+- Remove bbolt actorify implementation due to causing production issues.
+- Document missing environment variables in installation guide: `SLOG_LEVEL`, `COOKIE_PREFIX`, `FORCED_LANGUAGE`, and `TARGET_DISABLE_KEEPALIVE` ([#1086](https://github.com/TecharoHQ/anubis/pull/1086)).
+- Add validation warning when persistent storage is used without setting signing keys.
+- Fixed `robots2policy` to properly group consecutive user agents into `any:` instead of only processing the last one ([#925](https://github.com/TecharoHQ/anubis/pull/925)).
+- Make the `fast` algorithm prefer purejs when running in an insecure context.
+- Add the [`s3api` storage backend](./admin/policies.mdx#s3api) to allow Anubis to use S3 API compatible object storage as its storage backend.
+- Fix a "stutter" in the cookie name prefix so the auth cookie is named `techaro.lol-anubis-auth` instead of `techaro.lol-anubis-auth-auth`.
+- Make `cmd/containerbuild` support commas for separating elements of the `--docker-tags` argument as well as newlines.
+- Add the `DIFFICULTY_IN_JWT` option, which allows one to add the `difficulty` field in the JWT claims which indicates the difficulty of the token ([#1063](https://github.com/TecharoHQ/anubis/pull/1063)).
+- Ported the client-side JS to TypeScript to avoid egregious errors in the future.
+- Fixes concurrency problems with very old browsers ([#1082](https://github.com/TecharoHQ/anubis/issues/1082)).
+- Randomly use the Refresh header instead of the meta refresh tag in the metarefresh challenge.
+- Update OpenRC service to truncate the runtime directory before starting Anubis.
+- Make the git client profile more strictly match how the git client behaves.
+- Make the default configuration reward users using normal browsers.
+- Allow multiple consecutive slashes in a row in application paths ([#754](https://github.com/TecharoHQ/anubis/issues/754)).
+- Add option to set `targetSNI` to special keyword 'auto' to indicate that it should be automatically set to the request Host name ([424](https://github.com/TecharoHQ/anubis/issues/424)).
+- The Preact challenge has been removed from the default configuration. It will be deprecated in the future.
+- An open redirect when in subrequest mode has been fixed.
+
+### Potentially breaking changes
+
+#### Multiple checks at once has and-like semantics instead of or-like semantics
+
+Anubis lets you stack multiple checks at once with blocks like this:
+
+```yaml
+name: allow-prometheus
+action: ALLOW
+user_agent_regex: ^prometheus-probe$
+remote_addresses:
+  - 192.168.2.0/24
+```
+
+Previously, this only returned ALLOW if _any one_ of the conditions matched. This behaviour has changed to only return ALLOW if _all_ of the conditions match. I expect this to have some issues with user configs, however this fix is grave enough that it's worth the risk of breaking configs. If this bites you, please let me know so we can make an escape hatch.
+
+### Better error messages
+
+In order to make it easier for legitimate clients to debug issues with their browser configuration and Anubis, Anubis will emit internal error detail in base 64 so that administrators can chase down issues. Future versions of this may also include a variant that encrypts the error detail messages.
+
+### Bug Fixes
+
+Sometimes the enhanced temporal assurance in [#1038](https://github.com/TecharoHQ/anubis/pull/1038) and [#1068](https://github.com/TecharoHQ/anubis/pull/1068) could backfire because Chromium and its ilk randomize the amount of time they wait in order to avoid a timing side channel attack. This has been fixed by both increasing the amount of time a client has to wait for the metarefresh and preact challenges as well as making the server side logic more permissive.
+
+## v1.22.0: Yda Hext
+
+> Someone has to make an effort at reconciliation if these conflicts are ever going to end.
+
+In this release, we finally fix the odd number of CPU cores bug, pave the way for lighter weight challenges, make Anubis more adaptable, and more.
+
+### Big ticket items
+
+#### Proof of React challenge
+
+A new ["proof of React"](./admin/configuration/challenges/preact.mdx) has been added. It runs a simple app in React that has several chained hooks. It is much more lightweight than the proof of work check.
+
+#### Smaller features
+
+- The [`segments`](./admin/configuration/expressions.mdx#segments) function was added for splitting a path into its slash-separated segments.
+- Added possibility to disable HTTP keep-alive to support backends not properly handling it.
+- When issuing a challenge, Anubis stores information about that challenge into the store. That stored information is later used to validate challenge responses. This works around nondeterminism in bot rules. ([#917](https://github.com/TecharoHQ/anubis/issues/917))
+- One of the biggest sources of lag in Firefox has been eliminated: the use of WebCrypto. Now whenever Anubis detects the client is using Firefox (or Pale Moon), it will swap over to a pure-JS implementation of SHA-256 for speed.
+- Proof of work solving has had a complete overhaul and rethink based on feedback from browser engine developers, frontend experts, and overall performance profiling.
+- Optimize the performance of the pure-JS Anubis solver.
+- Web Workers are stored as dedicated JavaScript files in `static/js/workers/*.mjs`.
+- Pave the way for non-SHA256 solver methods and eventually one that uses WebAssembly (or WebAssembly code compiled to JS for those that disable WebAssembly).
+- Legacy JavaScript code has been eliminated.
+- When parsing [Open Graph tags](./admin/configuration/open-graph.mdx), add any URLs found in the responses to a temporary "allow cache" so that social preview images work.
+- The hard dependency on WebCrypto has been removed, allowing a proof of work challenge to work over plain (unencrypted) HTTP.
+- The Anubis version number is put in the footer of every page.
+- Add a default block rule for Huawei Cloud.
+- Add a default block rule for Alibaba Cloud.
+- Added support to use Traefik forwardAuth middleware.
+- Add X-Request-URI support so that Subrequest Authentication has path support.
+- Added glob matching for `REDIRECT_DOMAINS`. You can pass `*.bugs.techaro.lol` to allow redirecting to anything ending with `.bugs.techaro.lol`. There is a limit of 4 wildcards.

+Some phones have an odd number of CPU cores. This caused [interesting issues](https://anubis.techaro.lol/blog/2025/cpu-core-odd). This was fixed by [using `Math.trunc` to convert the number of CPU cores back into an integer](https://github.com/TecharoHQ/anubis/issues/1043).
+
+#### Smaller fixes
+
+- A standard library HTTP server log message about HTTP pipelining not working has been filtered out of Anubis' logs. There is no action that can be taken about it.
+- Added a missing link to the Caddy installation environment in the installation documentation.
+- Downstream consumers can change the default [log/slog#Logger](https://pkg.go.dev/log/slog#Logger) instance that Anubis uses by setting `opts.Logger` to your slog instance of choice ([#864](https://github.com/TecharoHQ/anubis/issues/864)).
+- The [Thoth client](https://anubis.techaro.lol/docs/admin/thoth) is now public in the repo instead of being an internal package.
+- [Custom-AsyncHttpClient](https://github.com/AsyncHttpClient/async-http-client)'s default User-Agent has an increased weight by default ([#852](https://github.com/TecharoHQ/anubis/issues/852)).
+- Add option for replacing the default explanation text with a custom one ([#747](https://github.com/TecharoHQ/anubis/pull/747))
+- The contact email in the LibreJS header has been changed.
+- Firefox for Android support has been fixed by embedding the challenge ID into the pass-challenge route. This also fixes some inconsistent issues with other mobile browsers.
+- The default `favicon` pattern in `data/common/keep-internet-working.yaml` has been updated to permit requests for png/gif/jpg/svg files as well as ico.
+- The `--cookie-prefix` flag has been fixed so that it is fully respected.
+- The default patterns in `data/common/keep-internet-working.yaml` have been updated to appropriately escape the '.' character in the regular expression patterns.
+- Add optional restrictions for JWT based on the value of a header ([#697](https://github.com/TecharoHQ/anubis/pull/697))
+- The word "hack" has been removed from the translation strings for Anubis due to incidents involving people misunderstanding that word and sending particularly horrible things to the project lead over email.
+- Bump AI-robots.txt to version 1.39
+- Inject adversarial input to break AI coding assistants.
+- Add better logging when using Subrequest Authentication.
+
+### Security-relevant changes
+
+- Add a server-side check for the meta-refresh challenge that makes sure clients have waited for at least 95% of the time that they should.
+
+#### Fix potential double-spend for challenges
+
+Anubis operates by issuing a challenge and having the client present a solution for that challenge. Challenges are identified by a unique UUID, which is stored in the database.
+
+The problem is that a challenge could potentially be used twice by a dedicated attacker making a targeted attack against Anubis. Challenge records did not have a "spent" or "used" field. In total, a dedicated attacker could solve a challenge once and reuse that solution across multiple sessions in order to mint additional tokens.
+
+This was fixed by adding a "spent" field to challenges in the data store. When a challenge is solved, that "spent" field gets set to `true`. If a future attempt to solve this challenge is observed, it gets rejected.
+
+With the advent of store based challenge issuance in [#749](https://github.com/TecharoHQ/anubis/pull/749), this means that these challenge IDs are [only good for 30 minutes](https://github.com/TecharoHQ/anubis/blob/e8dfff635015d6c906dddd49cb0eaf591326092a/lib/anubis.go#L130-L135d). Websites using the most recent version of Anubis have limited exposure to this problem.
+
+Websites using older versions of Anubis have a much more increased exposure to this problem and are encouraged to keep this software updated as often and as frequently as possible.
+
+Thanks to [@taviso](https://github.com/taviso) for reporting this issue.
+
+### Breaking changes
+
+- The "slow" frontend solver has been removed in order to reduce maintenance burden. Any existing uses of it will still work, but issue a warning upon startup asking administrators to upgrade to the "fast" frontend solver.
+- The legacy JSON based policy file example has been removed and all documentation for how to write a policy file in JSON has been deleted. JSON based policy files will still work, but YAML is the superior option for Anubis configuration.

+
+This could allow an attacker to craft an Anubis pass-challenge URL that forces a redirect to nonstandard URLs, such as the `javascript:` scheme which executes arbitrary JavaScript code in a browser context when the user clicks the "Try again" button.
+
+This has been fixed by disallowing any URLs without the scheme `http` or `https`.
+
+Additionally, the "Try again" button has been fixed to completely ignore the user-supplied redirect location. It now redirects to the home page (`/`).

+
+### Fixes
+
+#### Fix ["error: can't get challenge"](https://github.com/TecharoHQ/anubis/issues/869) when details about a challenge can't be found in the server side state
+
+v1.21.0 changed the core challenge flow to maintain information about challenges on the server side instead of only doing them via stateless idempotent generation functions and relying on details to not change. There was a subtle bug introduced in this change: if a client has an unknown challenge ID set in its test cookie, Anubis will clear that cookie and then throw an HTTP 500 error.
+
+This has been fixed by making Anubis throw a new challenge page instead.
+
+#### Fix event loop thrashing when solving a proof of work challenge
+
+Previously the "fast" proof of work solver had a fragment of JavaScript that attempted to only post an update about proof of work progress to the main browser window every 1024 iterations. This fragment of JavaScript was subtly incorrect in a way that passed review but actually made the workers send an update back to the main thread every iteration. This caused a pileup of unhandled async calls (similar to a socket accept() backlog pileup in Unix) that caused stack space exhaustion.
+
+This has been fixed in the following ways:
+
+1. The complicated boolean logic has been totally removed in favour of a worker-local iteration counter.
+2. The progress bar is updated by worker `0` instead of all workers.
+
+Hopefully this should limit the event loop thrashing and let ia32 browsers (as well as any environment with a smaller stack size than amd64 and aarch64 seem to have) function normally when processing Anubis proof of work challenges.
+
+#### Fix potential memory leak when discovering a solution
+
+In some cases, the parallel solution finder in Anubis could cause all of the worker promises to leak due to the fact the promises were being improperly terminated. This was fixed by having Anubis debounce worker termination instead of allowing it to potentially recurse infinitely.
+
+## v1.21.0: Minfilia Warde
+
+> Please, be at ease. You are among friends here.
+
+In this release, Anubis becomes internationalized, gains the ability to use system load as input to issuing challenges, finally fixes the "invalid response" after "success" bug, and more! Please read these notes before upgrading as the changes are big enough that administrators should take action to ensure that the upgrade goes smoothly.
+
+### Big ticket changes
+
+The biggest change is that the ["invalid response" after "success" bug](https://github.com/TecharoHQ/anubis/issues/564) is now finally fixed for good by totally rewriting how Anubis' challenge issuance flow works. Instead of generating challenge strings from request metadata (under the assumption that the values being compared against are stable), Anubis now generates random data for each challenge. This data is stored in the active [storage backend](./admin/policies.mdx#storage-backends) for up to 30 minutes. This also fixes [#746](https://github.com/TecharoHQ/anubis/issues/746) and other similar instances of this issue.
+
+In order to reduce confusion, the "Success" interstitial that shows up when you pass a proof of work challenge has been removed.
+
+#### Storage
+
+Anubis now is able to store things persistently [in memory](./admin/policies.mdx#memory), [on the disk](./admin/policies.mdx#bbolt), or [in Valkey](./admin/policies.mdx#valkey) (this includes other compatible software). By default Anubis uses the in-memory backend. If you have an environment with mutable storage (even if it is temporary), be sure to configure the [`bbolt`](./admin/policies.mdx#bbolt) storage backend.
+
+#### Localization
+
+Anubis now supports localized responses. Locales can be added in [lib/localization/locales/](https://github.com/TecharoHQ/anubis/tree/main/lib/localization/locales). This release includes support for the following languages:
+
+- [Brazilian Portugese](https://github.com/TecharoHQ/anubis/pull/726)
+- [Chinese (Simplified)](https://github.com/TecharoHQ/anubis/pull/774)
+- [Chinese (Traditional)](https://github.com/TecharoHQ/anubis/pull/759)
+- English
+- [Estonian](https://github.com/TecharoHQ/anubis/pull/783)
+- [Filipino](https://github.com/TecharoHQ/anubis/pull/775)
+- [French](https://github.com/TecharoHQ/anubis/pull/716)
+- [German](https://github.com/TecharoHQ/anubis/pull/741)
+- [Icelandic](https://github.com/TecharoHQ/anubis/pull/780)
+- [Italian](https://github.com/TecharoHQ/anubis/pull/778)
+- [Japanese](https://github.com/TecharoHQ/anubis/pull/772)
+- [Spanish](https://github.com/TecharoHQ/anubis/pull/716)
+- [Turkish](https://github.com/TecharoHQ/anubis/pull/751)
+
+If facts or local regulations demand, you can set Anubis default language with the `FORCED_LANGUAGE` environment variable or the `--forced-language` command line argument:
+
+```sh
+FORCED_LANGUAGE=de
+```
+
+#### Load average
+
+Anubis can dynamically take action [based on the system load average](./admin/configuration/expressions.mdx#using-the-system-load-average), allowing you to write rules like this:
+
+```yaml
+## System load based checks.
+# If the system is under high load for the last minute, add weight.
+- name: high-load-average
+  action: WEIGH
+  expression: load_1m >= 10.0 # make sure to end the load comparison in a .0
+  weight:
+    adjust: 20
+
+# If it is not for the last 15 minutes, remove weight.
+- name: low-load-average
+  action: WEIGH
+  expression: load_15m <= 4.0 # make sure to end the load comparison in a .0
+  weight:
+    adjust: -10
+```
+
+Something to keep in mind about system load average is that it is not aware of the number of cores the system has. If you have a 16 core system that has 16 processes running but none of them is hogging the CPU, then you will get a load average below 16. If you are in doubt, make your "high load" metric at least two times the number of CPU cores and your "low load" metric at least half of the number of CPU cores. For example:
+
+|      Kind | Core count | Load threshold |
+| --------: | :--------- | :------------- |
+| high load | 4          | `8.0`          |
+|  low load | 4          | `2.0`          |
+| high load | 16         | `32.0`         |
+|  low load | 16         | `8`            |
+
+Also keep in mind that this does not account for other kinds of latency like I/O latency. A system can have its web applications unresponsive due to high latency from a MySQL server but still have that web application server report a load near or at zero.
+
+### Other features and fixes
+
+There are a bunch of other assorted features and fixes too:
+
 - Add `COOKIE_SECURE` option to set the cookie [Secure flag](https://developer.mozilla.org/en-US/docs/Web/HTTP/Guides/Cookies#block_access_to_your_cookies)
 - Sets cookie defaults to use [SameSite: None](https://web.dev/articles/samesite-cookies-explained)
 - Determine the `BIND_NETWORK`/`--bind-network` value from the bind address ([#677](https://github.com/TecharoHQ/anubis/issues/677)).
- Implement localization system. Find locale files in lib/localization/locales/.
 - Implement a [development container](https://containers.dev/) manifest to make contributions easier.
 - Fix dynamic cookie domains functionality ([#731](https://github.com/TecharoHQ/anubis/pull/731))
 - Add option for custom cookie prefix ([#732](https://github.com/TecharoHQ/anubis/pull/732))
- Add translation for German language ([#741](https://github.com/TecharoHQ/anubis/pull/741))
- Remove the "Success" interstitial after a proof of work challenge is concluded.
- Anubis now has the concept of [storage backends](./admin/policies.mdx#storage-backends). These allow you to change how Anubis stores temporary data (in memory, on the disk, or in Valkey). If you run Anubis in an environment where you have a low amount of memory available for Anubis (eg: less than 64 megabytes), be sure to configure the [`bbolt`](./admin/policies.mdx#bbolt) storage backend.
- The challenge issuance and validation process has been rewritten from scratch. Instead of generating challenge strings from request metadata (under the assumption that the values being compared against are stable), Anubis now generates random data for each challenge. This data is stored in the active [storage backend](./admin/policies.mdx#storage-backends) for up to 30 minutes. Fixes [#564](https://github.com/TecharoHQ/anubis/issues/564), [#746](https://github.com/TecharoHQ/anubis/issues/746), and other similar instances of this issue.
- Add option for forcing a specific language ([#742](https://github.com/TecharoHQ/anubis/pull/742))
- Add translation for Turkish language ([#751](https://github.com/TecharoHQ/anubis/pull/751))
+- Make the [Open Graph](./admin/configuration/open-graph.mdx) subsystem and DNSBL subsystem use [storage backends](./admin/policies.mdx#storage-backends) instead of storing everything in memory by default.
 - Allow [Common Crawl](https://commoncrawl.org/) by default so scrapers have less incentive to scrape
+- The [bbolt storage backend](./admin/policies.mdx#bbolt) now runs its cleanup every hour instead of every five minutes.
+- Don't block Anubis starting up if [Thoth](./admin/thoth.mdx) health checks fail.
+- A race condition involving [opening two challenge pages at once in different tabs](https://github.com/TecharoHQ/anubis/issues/832) causing one of them to fail has been fixed.
+- The "Try again" button on the error page has been fixed. Previously it meant "try the solution again" instead of "try the challenge again".
+- In certain cases, a user could be stuck with a test cookie that is invalid, locking them out of the service for up to half an hour. This has been fixed with better validation of this case and clearing the cookie.
+- Start exposing JA4H fingerprints for later use in CEL expressions.
+- Add `/healthz` route for use in platform-based health checks.

 ### Potentially breaking changes

+We try to introduce breaking changes as much as possible, but these are the changes that may be relevant for you as an administrator:
+
+#### Challenge format change
+
+Previously Anubis did no accounting for challenges that it issued. This means that if Anubis restarted during a client, the client would be able to proceed once Anubis came back online.
+
+During the upgrade to v1.21.0 and when v1.21.0 (or later) restarts with the [in-memory storage backend](./admin/policies.mdx#memory), you may see a higher rate of failed challenges than normal. If this persists beyond a few minutes, [open an issue](https://github.com/TecharoHQ/anubis/issues/new).
+
+If you are using the in-memory storage backend, please consider using [a different storage backend](./admin/policies.mdx#storage-backends).
+
+#### Systemd service changes
+
 The following potentially breaking change applies to native installs with systemd only:

 Each instance of systemd service template now has a unique `RuntimeDirectory`, as opposed to each instance of the service sharing a `RuntimeDirectory`. This change was made to avoid [the `RuntimeDirectory` getting nuked any time one of the Anubis instances restarts](https://github.com/TecharoHQ/anubis/issues/748).

-If you configured Anubis' unix sockets to listen on `/run/anubis/foo.sock` for instance `anubis@foo`, you will need to configure Anubis to listen on `/run/anubis/foo/sock` and additionally configure your HTTP load balancer as appropriate.

+### Header-based overlay dispatch
+
+If you run BotStopper in a multi-tenant environment where each tenant needs its own branding, BotStopper supports the ability to use request header values to direct asset reads to different folders under your `OVERLAY_FOLDER`. One of the most common ways to do this is based on the HTTP Host of the request. For example, if you set `ASSET_LOOKUP_HEADER=Host` in BotStopper's environment:
+
+```text
+$OVERLAY_FOLDER
+├── static
+│   ├── css
+│   │   ├── custom.css

+## Custom HTML templates
+
+If you need to completely control the HTML layout of all Anubis pages, you can customize the entire page with `USE_TEMPLATES=true`. This uses Go's standard library [html/template](https://pkg.go.dev/html/template) package to template HTML responses. Your templates can contain whatever HTML you want. The only catch is that you MUST include `{{ .Head }}` in the `<head>` element for challenge pages, and you MUST include `{{ .Body }}` in the `<body>` element for all pages.
+
+In order to use this, you must define the following templates:
+
+| Template path                              | Usage                                           |

+| `$OVERLAY_FOLDER/templates/impressum.tmpl` | [Impressum](./configuration/impressum.mdx) page |
+
+:::note
+
+Currently HTML templates don't work together with [Header-based overlay dispatch](#header-based-overlay-dispatch). This is a known issue that will be fixed soon. If you enable header-based overlay dispatch, BotStopper will use the global `templates` folder instead of using the templates present in the overlay.
+
+:::
+
+Here are minimal (but working) examples for each template:
+
+<details>
+<summary>`challenge.tmpl`</summary>
+
+:::note
+
+You **MUST** include the `{{.Head}}` segment in a `<head>` tag. It contains important information for challenges to execute. If you don't include this, no clients will be able to pass challenges.
+

+# Client IP Headers
+
+Currently Anubis will always flatten the `X-Forwarded-For` when it contains multiple IP addresses. From right to left, the first IP address that is not in one of the following categories will be set as `X-Forwarded-For` in the request passed to the upstream.
+
+- Private (`XFF_STRIP_PRIVATE`, enabled by default)
+- CGNAT (always stripped)
+- Link-local Unicast (always stripped)
+
+```
+Incoming: X-Forwarded-For: 1.2.3.4, 5.6.7.8, 10.0.0.1
+Upstream: X-Forwarded-For: 5.6.7.8
+```
+
+This behavior will cause problems if the proxy in front of Anubis is from a public IP, such as Cloudflare, because Anubis will use the Cloudflare IP instead of your client's real IP. You will likely see all requests from your browser being blocked and/or an infinite challenge loop.
+
+```
+Incoming: X-Forwarded-For: REAL_CLIENT_IP, CF_IP
+Upstream: X-Forwarded-For: CF_IP
+```
+
+As a workaround, you should configure your web server to parse an alternative source (such as `CF-Connecting-IP`), or pre-process the incoming `X-Forwarded-For` with your web server to ensure it only contains the real client IP address, then pass it to Anubis as `X-Forwarded-For`.
+
+If you do not control the web server upstream of Anubis, the `custom-real-ip-header` command line flag accepts a header value that Anubis will read the real client IP address from. Anubis will set the `X-Real-IP` header to the IP address found in the custom header.
+
+The `X-Real-IP` header will be automatically inferred from `X-Forwarded-For` if not set, setting it explicitly is not necessary as long as `X-Forwarded-For` contains only the real client IP. However setting it explicitly can eliminate spoofed values if your web server doesn't set this.
+
+See [Cloudflare](environments/cloudflare.mdx) for an example configuration.

+
+The `preact` challenge sends the browser a simple challenge that makes it run very lightweight JavaScript that proves the client is able to execute client-side JavaScript. It uses [Preact](https://www.npmjs.com/package/preact) (a lightweight client side web framework in the vein of React) to do this.

+### Using the system load average
+
+In Unix-like systems (such as Linux), every process on the system has to wait its turn to be able to run. This means that as more processes on the system are running, they need to wait longer to be able to execute. The [load average](<https://en.wikipedia.org/wiki/Load_(computing)>) represents the number of processes that want to be able to run but can't run yet. This metric isn't the most reliable to identify a cause, but is great at helping to identify symptoms.
+
+Anubis lets you use the system load average as an input to expressions so that you can make dynamic rules like "when the system is under a low amount of load, dial back the protection, but when it's under a lot of load, crank it up to the mix". This lets you get all of the blocking features of Anubis in the background but only really expose Anubis to users when the system is actively being attacked.
+
+This is best combined with the [weight](../policies.mdx#request-weight) and [threshold](./thresholds.mdx) systems so that you can have Anubis dynamically respond to attacks. Consider these rules in the default configuration file:
+
+```yaml
+## System load based checks.
+# If the system is under high load for the last minute, add weight.
+- name: high-load-average
+  action: WEIGH
+  expression: load_1m >= 10.0 # make sure to end the load comparison in a .0
+  weight:
+    adjust: 20
+
+# If it is not for the last 15 minutes, remove weight.
+- name: low-load-average
+  action: WEIGH
+  expression: load_15m <= 4.0 # make sure to end the load comparison in a .0
+  weight:
+    adjust: -10
+```
+
+This combination of rules makes Anubis dynamically react to the system load and only kick in when the system is under attack.
+
+Something to keep in mind about system load average is that it is not aware of the number of cores the system has. If you have a 16 core system that has 16 processes running but none of them is hogging the CPU, then you will get a load average below 16. If you are in doubt, make your "high load" metric at least two times the number of CPU cores and your "low load" metric at least half of the number of CPU cores. For example:
+
+|      Kind | Core count | Load threshold |
+| --------: | :--------- | :------------- |
+| high load | 4          | `8.0`          |
+|  low load | 4          | `2.0`          |
+| high load | 16         | `32.0`         |
+|  low load | 16         | `8`            |
+
+Also keep in mind that this does not account for other kinds of latency like I/O latency. A system can have its web applications unresponsive due to high latency from a MySQL server but still have that web application server report a load near or at zero.
+
 ## Functions exposed to Anubis expressions

 Anubis expressions can be augmented with the following functions:

+### `missingHeader`

+Available in `bot` expressions.
+
+```ts
+function missingHeader(headers: Record<string, string>, key: string) bool

+
+`missingHeader` returns `true` if the request does not contain a header. This is useful when you are trying to assert behavior such as:

+  weight:
+    adjust: 10
+  expression:
+    all:

+      - missingHeader(headers, "Sec-Ch-Ua")
+```

+### `regexSafe`
+
+Available in `bot` expressions.
+
+```ts
+function regexSafe(input: string): string;
+```
+
+`regexSafe` takes a string and escapes it for safe use inside of a regular expression. This is useful when you are creating regular expressions from headers or variables such as `remoteAddress`.
+
+| Input                     | Output                          |
+| :------------------------ | :------------------------------ |
+| `regexSafe("1.2.3.4")`    | `1\\.2\\.3\\.4`                 |
+| `regexSafe("techaro.lol")` | `techaro\\.lol`                 |
+| `regexSafe("star*")`      | `star\\*`                       |
+| `regexSafe("plus+")`      | `plus\\+`                       |
+| `regexSafe("{braces}")`   | `\\{braces\\}`                  |
+| `regexSafe("start^")`     | `start\\^`                      |
+| `regexSafe("back\\slash")` | `back\\\\slash`                 |
+| `regexSafe("dash-dash")`  | `dash\\-dash`                   |
+
+### `segments`
+
+Available in `bot` expressions.
+
+```ts
+function segments(path: string): string[];
+```
+
+`segments` returns the number of slash-separated path segments, ignoring the leading slash. Here is what it will return with some common paths:
+
+| Input                    | Output                 |
+| :----------------------- | :--------------------- |
+| `segments("/")`          | `[""]`                 |
+| `segments("/foo/bar")`   | `["foo", "bar"] `      |
+| `segments("/users/xe/")` | `["users", "xe", ""] ` |
+
+:::note
+
+If the path ends with a `/`, then the last element of the result will be an empty string. This is because `/users/xe` and `/users/xe/` are semantically different paths.
+
+:::
+
+This is useful if you want to write rules that allow requests that have no query parameters only if they have less than two path segments:
+
+```yaml
+- name: two-path-segments-no-query
+  action: ALLOW
+  expression:
+    all:
+      - size(query) == 0
+      - size(segments(path)) < 2
+```
+
+### DNS Functions
+
+Anubis can also perform DNS lookups as a part of its expression evaluation. This can be useful for doing things like checking for a valid [Forward-confirmed reverse DNS (FCrDNS)](https://en.wikipedia.org/wiki/Forward-confirmed_reverse_DNS) record.
+
+#### `arpaReverseIP`
+
+Available in `bot` expressions.
+
+```ts
+function arpaReverseIP(ip: string): string;
+```
+
+`arpaReverseIP` takes an IP address and returns its value in [ARPA notation](https://www.ietf.org/rfc/rfc2317.html). This can be useful when matching PTR record patterns.
+
+| Input                          | Output                                                               |
+| :----------------------------- | :------------------------------------------------------------------- |
+| `arpaReverseIP("1.2.3.4")`     | `4.3.2.1`                                                            |
+| `arpaReverseIP("2001:db8::1")` | `1.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.8.b.d.0.1.0.0.2` |
+
+#### `lookupHost`
+
+Available in `bot` expressions.
+
+```ts
+function lookupHost(host: string): string[];
+```
+
+`lookupHost` performs a DNS lookup for the given hostname and returns a list of IP addresses.
+
+```yaml
+- name: cloudflare-ip-in-host-header
+  action: DENY
+  expression: '"104.16.0.0" in lookupHost(headers["Host"])'
+```
+
+#### `reverseDNS`
+
+Available in `bot` expressions.
+
+```ts
+function reverseDNS(ip: string): string[];
+```
+
+`reverseDNS` takes an IP address and returns the DNS names associated with it. This is useful when you want to check PTR records of an IP address.
+
+```yaml
+- name: allow-googlebot
+  action: ALLOW
+  expression: 'reverseDNS(remoteAddress).endsWith(".googlebot.com")'
+```
+
+::: warning
+
+Do not use this for validating the legitimacy of an IP address. It is possible for DNS records to be out of date or otherwise manipulated. Use [`verifyFCrDNS`](#verifyfcrdns) instead for a more reliable result.
+
+:::
+
+#### `verifyFCrDNS`
+
+Available in `bot` expressions.
+
+```ts
+function verifyFCrDNS(ip: string): bool;
+function verifyFCrDNS(ip: string, pattern: string): bool;
+```
+
+`verifyFCrDNS` checks if the reverse DNS of an IP address matches its forward DNS. This is a common technique to filter out spam and bot traffic. `verifyFCrDNS` comes in two forms:
+
+- `verifyFCrDNS(remoteAddress)` will check that the reverse DNS of the remote address resolves back to the remote address. If no PTR records, returns true.
+- `verifyFCrDNS(remoteAddress, pattern)` will check that the reverse DNS of the remote address is matching with pattern and that name resolves back to the remote address.
+
+This is best used in rules like this:
+
+```yaml
+- name: require-fcrdns-for-post
+  action: DENY
+  expression:
+    all:
+      - method == "POST"
+      - "!verifyFCrDNS(remoteAddress)"
+```
+
+Here is an another example that allows requests from telegram:
+
+```yaml
+- name: telegrambot
+  action: ALLOW
+  expression:
+    all:
+      - userAgent.matches("TelegramBot")
+      - verifyFCrDNS(remoteAddress, "ptr\\.telegram\\.org$")
+```
+
 ## Life advice

 Expressions are very powerful. This is a benefit and a burden. If you are not careful with your expression targeting, you will be liable to get yourself into trouble. If you are at all in doubt, throw a `CHALLENGE` over a `DENY`. Legitimate users can easily work around a `CHALLENGE` result with a [proof of work challenge](../../design/why-proof-of-work.mdx). Bots are less likely to be able to do this.

 ## Configuring allowed redirect domains

-By default, Anubis will limit redirects to be on the same HTTP Host that Anubis is running on (EG: requests to yoursite.com cannot redirect outside of yoursite.com). If you need to set more than one domain, fill the `REDIRECT_DOMAINS` environment variable with a comma-separated list of domain names that Anubis should allow redirects to.
+By default, Anubis may redirect to any domain which could cause security issues in the unlikely case that an attacker passes a challenge for your browser and then tricks you into clicking a link to your domain.
+One can restrict the domains that Anubis can redirect to when passing a challenge by setting up `REDIRECT_DOMAINS` environment variable.
+If you need to set more than one domain, fill the environment variable with a comma-separated list of domain names.
+There is also glob matching support. You can pass `*.bugs.techaro.lol` to allow redirecting to anything ending with `.bugs.techaro.lol`. There is a limit of 4 wildcards.

 :::note

-These domains are _an exact string match_, they do not support wildcard matches.
