## Timeline of updates

- **resolved** 2025-06-18 18:47 UTC: On June 18, 2025, between 08:21 UTC and 18:47 UTC, some Actions jobs experienced intermittent failures downloading from the Actions Cache service. During the incident, 17% of workflow runs experienced cache download failures, resulting in a warning message in the logs and performance degradation. The disruption was caused by a network issue in our database systems that led to a database replica getting out of sync with the primary. We mitigated the incident by routing cache download url requests to bypass the out-of-sync replica until it was fully restored. To prevent this class of incidents, we are developing capability in our database system to more robustly bypass out-of-sync replicas. We are also implementing improved monitoring to help us detect similar issues more quickly going forward.
