GitHub resolves outage affecting Pull Requests and Copilot
GitHub experienced a series of service disruptions in late October and early November 2026, impacting core development tools and AI features. The most recent incident, resolved on November 4, involved degraded availability for Pull Requests, Git Operations, and Issues. GitHub attributed the issue to a specific client version and deployed a mitigation that restored stability by 10:01 UTC.
Key points
- GitHub resolved a November 4 outage affecting Pull Requests and Git Operations caused by a client version issue.
- Copilot experienced outages on November 2 and October 28 due to upstream model provider failures for several GPT models.
- An October 30 incident delayed Actions and Webhooks due to a network gateway maintenance error causing a connection storm.
Earlier in the month, GitHub Copilot faced multiple outages due to upstream model provider issues. On November 2, the GPT-5.4 Nano model experienced elevated errors, while an October 28 incident affected six models, including GPT-5.3-Codex and GPT-6.1 Sol. GitHub advised users to switch models during these periods. Additionally, an October 30 incident caused delays in Actions, Pages, and Webhooks, which GitHub traced to a network gateway maintenance event that triggered a connection storm with a 90% failure rate.
These incidents highlight ongoing challenges in maintaining reliability for both traditional Git operations and integrated AI services. GitHub has stated it is implementing changes to retry behaviors and infrastructure resilience to prevent similar issues.
