On October 29th, 2025 between 14:07 UTC and 23:15 UTC, multiple GitHub services were degraded:

• Users of Codespaces experienced failures connecting to new and existing Codespaces through VSCode Desktop or Web. On average the Codespace connection error rate was 90% and peaked at 100% across all regions throughout the incident period.
• GitHub Actions larger hosted runners experienced degraded performance, with 0.5% of overall workflow runs and 9.8% of larger hosted runner jobs failing or not starting within 5 minutes. These recovered by 20:40 UTC.
• The GitHub Enterprise Importer service was degraded, with some users experiencing migration failures during git push operations and most users experiencing delayed migration processing. We are working to reduce critical path dependencies on the service provider and gracefully degrade experiences where possible so that we are more resilient to future dependency outages.
