      	On October 24th, 2025, between 09:00 UTC and 10:10 UTC, GitHub Enterprise Cloud with Data Residency in the EU experienced degraded performance. During this time, approximately 13% of GitHub Actions runs failed and an additional 18% were delayed by more than 5 minutes. Around 2% of authorization service requests failed, resulting in instability for a small number of users viewing user-owned resources. Copilot services also saw degradation, with around 14% of requests to Copilot failing during this time period.  
The incident was caused by an unexpected load pattern in GitHub Actions, which led to instability in the service and some shared dependencies. We mitigated the issue by identifying and blocking the actors responsible for this pattern. We are working to improve the resilience of our services to unusual load scenarios and are pursuing performance optimizations to help prevent similar incidents in the future.
