Summary
GitHub opened the incident at 13:40:03 UTC after failures affected GitHub.com services, with repository-content downloads later reported at roughly a 50% error rate. The status page continued to record Copilot authentication failures and residual impact during the window.
Why it matters
GitHub is a source-hosting, review and automation dependency, so outages can stop source retrieval and agent-assisted delivery even when application runtimes remain healthy.
