GitHub's CTO on a 7 hour 47 minute outage: "we let you down"
On August 17, 2026 GitHub served elevated errors from 13:28 to 21:15 UTC, 7 hours and 47 minutes, across Issues, Pull Requests, the API, Actions and Copilot. Web and API error rates peaked near 20 percent, raw content downloads near 50 percent, and Copilot authentication kept failing after other services recovered. In an account published August 21, CTO Vladimir Fedorov wrote: "If you were trying to ship software that day, we let you down." Neither incident came from a code or config change; the platform failed to scale with demand, with autoscaling problems and a retry storm from VS Code clients making it worse. GitHub now handles about 2.9 billion commits a month, up from 1.4 billion in April.
