GitHub Availability Report: February 2025

In February 2025, GitHub experienced two performance incidents impacting its services. On February 25, notifications were delayed for over two hours due to worker pools operating near capacity, with 10% of notifications taking over 10 minutes to deliver. This was mitigated by scaling the service and increasing baseline capacity for future demand. Earlier, on February 3, a 30-minute outage occurred when a system component deployment resulted in missing Docker images, disrupting migration tools for all users. This was resolved by rolling back to a stable version, and GitHub has since improved test coverage and workflows to validate critical dependencies.
