On September 25th, 2024 from 18:32 UTC to 19:13 UTC, Actions service experienced a degradation during a production deployment, leading to actions failing to be downloaded at the start of a job. On average, 21% of Actions workflow runs failed to start during the course of the incident. The issue was traced back to a bug in an internal service responsible for generating the URLs used by the Actions runner to download actions.
To mitigate the impact, we rolled back the affecting deployment. We are implementing new monitors to improve our detection and response time for this class of issues in the future.
