On May 11th, 2026, between 14:00 UTC and 14:33 UTC, HTTP-based Git read operations were degraded. On average, the error rate was 2.8% and peaked at 7.5% of requests to the service. This was due to resource exhaustion in a networking gateway between GitHub.com’s frontend service for Git operations and a dependency service that performs authentication and authorization. Following the initial spike, the frontend service became stuck in a degraded state in one of our data centers, increasing time to mitigation.
We mitigated the incident by scaling the networking gateway and re-deploying the frontend service.
To reduce our time to detection and mitigation in the future, we are adding auto-scaling to the networking gateway, and resolving a bug which caused the frontend service to remain degraded.
