Trigger
Elevated traffic to portions of GitHub.com that exceeded previously provisioned capacity for specific request types.
Detection
Intermittent 500 errors were detected, and the teams were actively investigating the cause and working on mitigation.
Resolution
Increased available capacity for web request handling to relieve pressure on constrained pools, and re-routed critical authentication endpoints to a different traffic pool to ensure sufficient isolation and headroom for login related traffic.
Root Cause
Elevated traffic to portions of GitHub.com that exceeded previously provisioned capacity for specific request types.
