Between 4:30 AM and 9:30 AM PDT on May 11, 2026, some Percy builds took longer than usual to complete due to increased database contention. Builds were not lost - only delayed. The issue has been mitigated and processing times are back to normal. We're investigating the root cause to prevent recurrence in future.

We are currently observing degraded performance from 6.30 AM - 7.45 AM PDT in Percy, primarily affecting build processing times and dashboard responsiveness. Our investigation indicates that this is due to an ongoing AWS US-East-1 regional outage impacting one of our critical third-party services - LaunchDarkly - which we use for configuration management and feature flag delivery. We are actively monitoring the situation and working with teams to mitigate impact. Builds may take longer to start or complete until the upstream issue is resolved.
