GitHub encountered a significant global outage on 17 August that affected almost every core function of the platform.
Home users, corporations, and Microsoft services all reported problems as the disruption spread across the web interface, API, Issues, Pull Requests, Actions, Webhooks, Pages, Git Operations, and Copilot.
At the height of the incident roughly 20 percent of requests to the website and API returned errors, while loads of repository archives and raw content saw failure rates near 50 percent.
Enterprise authentication systems including SAML and OIDC, as well as SCIM and Team Sync, were also impacted.
Codespaces continued to function normally throughout the event.
The first signs of degradation appeared around 13:40 UTC, after which problems sequentially emerged in API Requests, Actions, Webhooks, Issues, Pull Requests, Copilot, Pages, and Git operations.
GitHub engineers identified the faulty component and applied remediation steps. Latest updates indicate services are recovering, although error levels remain marginally above normal and the incident remains open.
Users simultaneously reported issues with other Microsoft ecosystem products such as Teams and Copilot. Experts suggested a possible connection to network problems at Amazon Web Services, but GitHub has not officially confirmed this hypothesis or disclosed the root cause.
