We are currently observing degraded performance from 12:20 PM PDT to 1 PM PDT \[20th October\] 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 . 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.
