Incident Report

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).
