- **postmortem** 2026-05-15 17:12 UTC: On May 7, a production deployment introduced a database locking conflict that caused Quay.io to become unhealthy. Image pulls were intermittently degraded for approximately 30 minutes and image pushes were unavailable for approximately 3 hours. The team failed over to a secondary region to restore pulls, then reverted the deployment to fully restore service. We are implementing multi-phase deployment rollouts, stricter canary processes, and health probe improvements to prevent recurrence.
