## Updates from Percy
### 2025-10-20 13:30 UTC: resolved
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.
