GitHub Outage History

GitHub experienced a service incident where audit logs became unavailable due to performance issues affecting some GitHub services. The outage lasted approximately 5 minutes before being resolved. GitHub has indicated they will provide a detailed root cause analysis once available.

GitHub's code search service experienced a major disruption lasting 8.7 hours due to issues with the ingestion pipeline that degraded result freshness, followed by a deployment that caused most search requests to fail. During the incident, users experienced failed code search queries and stale results for changes made after 07:00 UTC. The service was restored after GitHub stabilized the code search infrastructure and gradually reintroduced production traffic.

GitHub Copilot experienced degraded performance for 2.8 hours, with users encountering increased latency and intermittent errors when viewing or creating agent sessions. The service degradation was mitigated and performance stabilized back to baseline levels. The incident has been fully resolved with a detailed root cause analysis to follow.

GitHub experienced a 6.3-hour incident where Pull Requests suffered from elevated 500 errors, timeouts, and degraded performance, with users encountering intermittent failures when viewing or interacting with pull requests. The issue initially affected multiple GitHub services but was gradually mitigated through infrastructure fixes, ultimately impacting less than 1% of requests by the end. The incident was fully resolved after multiple mitigation efforts were applied across GitHub's infrastructure.

GitHub experienced issues with metered billing report generation that caused high failure rates for billing reports and intermittent problems with metered usage graphs on billing pages. The incident also resulted in widespread 500 errors and timeouts across GitHub services due to problems with a billing-related data store. The issue was resolved after 1.4 hours by applying mitigations to the affected data store and redeploying core services.

GitHub experienced elevated delays in Actions workflow runs and Pull Request status updates for 27 minutes. The degraded performance affected users' ability to run automated workflows and receive timely status updates on pull requests. The issue was mitigated and resolved after monitoring confirmed system stability.

GitHub experienced elevated error rates and degraded performance across multiple services including Actions, Issues, Pull Requests, Webhooks, Codespaces, and login functionality for 38 minutes. Users encountered errors when trying to access these features during the incident. The issue was resolved with most services showing signs of recovery, and GitHub indicated a detailed root cause analysis would be shared.

GitHub experienced a service outage affecting multiple services including the main landing page and repository links, which users reported as not loading. The incident was classified as minor and lasted 4 minutes while GitHub investigated reports of impacted performance. The status remained under investigation during the brief outage period.

GitHub experienced performance issues affecting some of their services for 54 minutes on March 22, 2026. The incident involved intermittently high latency and errors specifically impacting Git operations. The service disruption was resolved and GitHub indicated they would provide a detailed root cause analysis.

GitHub experienced a major disruption affecting Copilot Coding Agent sessions for 1.1 hours, with users unable to start or view agent sessions. The incident was caused by widespread issues that GitHub identified and resolved through mitigation efforts.
