GitHub ties August 17 outage to capacity shortfall

Summary Central US capacity failed at peak traffic, disrupting GitHub and Copilot for 7 hours 47 minutes.

The details

  • The outage affected github.com, authentication, Actions, APIs, pull requests, issues, and Copilot for 7 hours 47 minutes.
  • GitHub says a critical Central US infrastructure component failed to scale at a new traffic peak, not from code or configuration changes.
  • Client-side retries from failing Copilot services increased recovery traffic, requiring mitigation before traffic could be safely restored.
  • Since April, monthly commits grew from 1.4 billion to 2.9 billion.
  • GitHub has added more than 3 million CPU cores and 120 PB of high-speed storage.
  • Azure now serves roughly 58% of platform load.
  • Azure serves half of Git operations.
