AU - Incident with Actions
Resolved - On September 24, between 15:00 and 17:25 UTC, customers using the Australia stamp of GitHub Enterprise Cloud experienced failures and delays when running workflows on GitHub Actions. During this period, processing of Actions webhook events and scheduled invocations was paused. After the incident was resolved, delayed webhooks were delivered, and approximately 98% of Actions events were eventually processed.

The incident was caused by an existing misconfiguration in our stream processing system preventing automated recovery when multiple brokers went unavailable. When these failures occurred simultaneously, the misconfigured threshold prevented jobs from being enqueued.

We have corrected this configuration across all environments, and implemented tests which ensure future configuration conformance and prevent similar issues.

AU - Disruption with some GitHub services
Resolved - On September 15th between 17:55 and 18:20 UTC, Copilot experienced degraded availability for all features. This was due a partial deployment of a feature flag to a global rate limiter. The flag triggered behavior that unintentionally rate limited all requests, resulting in 100% of them returning 403 errors. The issue was resolved by reverting the feature flag which resulted in immediate recovery.

The root cause of the incident was from an undetected edge case in our rate limiting logic. The flag was meant to scale down rate limiting for a subset of users, but unintentionally put our rate limiting configuration into an invalid state.

To prevent this from happening again, we have addressed the bug with our rate limiting. We are also adding additional monitors to detect anomalies in our traffic patterns, which will allow us to identify similar issues during future deployments. Furthermore, we are exploring ways to test our rate limit scaling in our internal environment to enhance our pre-production validation process.
