GoKawiilPeople 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 up until 5:15PM ET. The platform's status page originally noted there were problems on several fronts, including with API requests, pull requests and webhooks. Copilot was also affected, so those using the platform for AI coding might be experiencing issues as well.
"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. "We are currently performing mitigations based on our investigation thus far and are monitoring for improvement."
At 1:34PM, GitHub said it had pinpointed "the problematic component" and taken "corrective actions." It said webhooks, API requests and pull requests were up and running again. However, it was still seeing issues with Copilot and the GitHub website as of 3:05PM, and it wasn't until 5:15PM that the company gave the all-clear.
It's not yet public what caused this outage. It's at least the second major outage to hit a Microsoft platform in the last few weeks after many Xbox services were knocked offline for several hours late last month. Github said it would share a "detailed root cause analysis" as soon as it has one.
Update, August 17, 2026, 5:41PM ET: This story was updated after publish several times, most recently to note that the outage was over.
