GitHub, the widely used developer platform, has been experiencing a major global outage since Monday, August 17, in the morning.
The downtime disrupted millions of developers worldwide who rely on the service for coding, collaborating, and deployment.
The outage started around 9:40 a.m. EDT as per GitHub’s status page. The company confirmed that it is currently investigating “performance problems” affecting key services including API requests, actions, issues, pull requests, webhooks, and Copilot.
There are around 20% reported errors for web experiences and API traffic, while archive downloads and raw repository content downloads are failing at an alarming 50% rate. Authentication services including SAML, OIDC, SCIM, and Team Sync have also been affected, preventing some enterprise users from accessing the platform entirely.
More than 15,000 users reported issues on Downdetector by mid-morning, with developers taking to social media to express frustration as deployment stalled. The outage marks the 13th incident in August alone, raising concerns from developers about the platform’s reliability. GitHub has not disclosed the underlying cause but says it is “currently performing mitigations.”
GitHub, which Microsoft acquired in 2018, serves over 100 million developers worldwide.
