Resolved on May 15, 2025.
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 [email protected] — 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
