GitHub went down worldwide on August 17, 2026, taking out tools many teams depend on for development and day-to-day business workflows for almost eight hours. GitHub said the outage hit the GitHub web interface, the GitHub API, GitHub Actions, GitHub webhooks, pull requests, GitHub Copilot, and enterprise identity features.
The company said the incident started at 13:40 UTC and wasn’t fully resolved until 21:15 UTC. At the worst point, GitHub reported roughly a 20% error rate across web and API traffic, while archive downloads and raw content requests were failing at about 50%. For your team, that translated into trouble across the web interface, API requests, Actions, webhooks, pull requests, Copilot, and enterprise identity features such as SAML, OIDC, SCIM, and Team Sync. The result was shaky code access, stalled pipelines, blocked deployments, and sign-ins that simply failed.
GitHub and Microsoft said engineers were investigating as the failures spread and put corrective measures in place to bring services back. Customers are still likely to want a much fuller post-incident account: what actually broke, why so many systems went down at the same time, and what protections will be added to keep it from happening again.
If GitHub is part of your daily routine, this outage lands a little harder. GitHub’s status history reportedly showed eight degradation events in July alone, during a period of heavier automated development, GitHub’s Azure migration, estimates that commit volume is rising from 2025 to 2026, and GitHub’s own plan to expand capacity by 30x. If you want to keep an eye on service availability, GitHub’s status page is the place to check.
