Is AdGuard Down Right Now? Check if there is a current outage ongoing.

We are currently investigating this issue.

Due to some global routing issues some AdGuard DNS locations are overloaded and may have degraded performance

The scheduled maintenance has been completed.

Scheduled maintenance is currently in progress. We will provide updates as necessary.

We're performing internal infrastructure updates during this time window.AdGuard services may be shortly unavailable during this time.Affected services:* All websites* VPN (new connections)* DNS: dashboard & custom rules update. DNS servers won't be affected. Queries log will not be lost

Due to internal services misconfiguration AdGuard websites was partially unavailable for some users during ~2 hours. All problems are solved now; we'll add postmortem about this situation later.

Due to an overwhelming number of requests to our authentication backend at the time, an internal issue occurred that temporarily disrupted its performance, which resulted in its partial unavailability. A permanent fix is in works, and in the meantime we're implementing a temporary solution to keep the backend operational. We would like to apologize for the inconvenience.

We're deploying anti-DDOS measures. By the way, this is a great moment to remind everyone that AdGuard filters are among the most popular and actively maintained in the world. They’re developed with the help of a large and passionate community, and we welcome any and all contributions. You can suggest your own filtering rules or let us know where ads are still slipping through. Learn more in our filter repository: 👉 https://github.com/AdguardTeam/AdGuardFilters The real strength of ad blockers lies in the community — it’s the result of the work of thousands of people. Huge thanks to everyone who’s helping make the web cleaner.

AdGuard website is currently under a DDoS attack and may be experiencing slow performance. Judging by the nature of the attack, the attacker is very unhappy that AdGuard blocks ads on movie websites (likely pirated ones), as we initially observed millions of HTTP requests like: “StopUpdatingRulesForMoviesWebsites=stopedtingformovieswebsites@gmail.com” Naturally, we will continue blocking ads on such sites — and we’ll strive to do it even more quickly and effectively than before (if that’s even possible).

Last night, the AdGuard website was subjected to a massive DDoS attack. Our team took all necessary actions to mitigate the situation. As part of the mitigation process, we enabled a manual anti-DDoS mode based on a set of predefined rules. Unfortunately, at this stage, a misconfiguration occurred: an overly broad rule was deployed, which disrupted connectivity to our payment gateway. As a result, for approximately 5.5 hours, information about completed purchases was not reaching AdGuard. This led to a failure to issue new licenses and activation keys. At the time of writing, the issue has been fully resolved. All payments made during the affected time window should now be processed correctly. If you are still experiencing any issues, please contact us at support@adguard.com — we will do our best to help you as quickly as possible. To prevent such incidents in the future, we will take the following steps: * Decouple payment processing logic from other systems * Avoid using overly broad anti-DDoS rules * Apply new rules with greater scrutiny and caution
