GitHub Experiences Major Global Outage Affecting API, Actions, Copilot and Multiple Core Services
On August 17, GitHub suffered a widespread outage that impacted nearly all major platform functions including the web interface, API, Issues, Pull Requests, Actions, Webhooks, Pages, Git Operations, and Copilot. Approximately 20% of requests to the site and API failed during peak impact, with archive and raw repository content loads reaching around 50% error rates. Corporate authentication mechanisms such as SAML and OIDC, along with SCIM and Team Sync services, were also disrupted while Codespaces remained operational. The incident began around 13:40 UTC with progressive degradation across components, prompting GitHub to identify and mitigate the root cause. Services are gradually recovering but error rates remain slightly elevated, and the incident has not yet been fully closed. Parallel issues were reported in other Microsoft services including Teams and Copilot, with unconfirmed speculation linking the event to Amazon Web Services network problems.
