GitHub availability report: January 2026

In January 2026, GitHub experienced two significant incidents affecting its services, primarily due to configuration and infrastructure issues. On January 13, a service outage in GitHub Copilot was caused by a configuration error during a model update, resulting in high error rates and impacting various chat features; the problem was exacerbated by degraded availability from the upstream provider, OpenAI, but was mitigated by rolling back the changes. On January 15, an infrastructure update led to increased latency and timeouts across multiple GitHub services, affecting both authenticated and unauthenticated users, due to unexpected resource contention from upgrading data stores to a new major version; the issue was resolved by reverting to a stable version. GitHub is taking measures to strengthen monitoring, improve test environments, and refine upgrade validation processes to prevent future occurrences and enhance response times.
