If you heard lots of grumbling in coffee shops today, GitHub's outage may be why. People who do more than vibe coding to build apps and websites were in a bit of a tizzy this Monday, when developer platform GitHub had an outage that took many hours to resolve. Errors began at around 9:40AM ET, and continued in some form up until 5:15PM ET.

The platform's status page originally noted problems on several fronts, including with API requests, pull requests and webhooks. Copilot was also affected. "We are experiencing high error rates around 20 percent for web experiences and API traffic. Archive downloads and raw repository content downloads are experiencing an approximate 50 percent error rate," read an update posted just before 11AM.

At 1:34PM, GitHub said it had pinpointed "the problematic component" and taken "corrective actions." Webhooks, API requests and pull requests were up and running again, though issues with Copilot and the GitHub website persisted until 3:05PM. The all-clear came at 5:15PM. It's not yet public what caused this outage. It's at least the second major outage to hit a Microsoft platform in recent weeks after many Xbox services were knocked offline late last month. GitHub said it would share a "detailed root cause analysis" soon.
