Last text from Microsoft

On October 6, 2026, from 19:44 to 19:50 UTC, GitHub experienced a service outage with elevated error rates peaking at 1.30% of all requests, totaling approximately 1.16 million failed requests. This impacted 12 services across GitHub, including Pull Requests, Webhooks, Repos, OAuth, Git over SSH, Codespaces, and Gists. The incident was triggered by GitHub Enterprise Importer (GEI) making multiple, long duration queries which saturated a database connection pool. Recovery was seen at approximately 19:50 UTC once the migration's calls stopped; GEI migrations were reenabled at 23:32 UTC after a code fix was merged.<br /><br />We have completed a detailed root-cause review and are implementing improved database-health safeguards. We will continue to review and add additional safeguards to prevent future recurrence.

  2. Investigating

    We are deploying a mitigation and plan to resume migrations shortly thereafter

  3. Investigating

    We are working towards a mitigation that will allow us to resume processing enterprise migrations.

  4. Investigating

    All services are functioning normally except for enterprise migrations, which are still paused. They will resume soon.

  5. Monitoring

    The degradation has been mitigated. We are monitoring to ensure stability.
