Developers building apps and websites faced some disruption Monday after GitHub experienced an outage that lasted several hours.
GitHub’s status page shows that the problems started around 9:40 a.m. ET and lasted in some form until 5:15 p.m. ET. Several services were affected, including API requests, pull requests, webhooks, and Copilot, the company’s AI coding assistant.
In an update posted just before 11 a.m. ET, GitHub said:
“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. We are currently performing mitigations based on our investigation thus far and are monitoring for improvement.”
At 1:34 p.m. ET, GitHub said it had identified the “problematic component” and taken steps to fix it. Webhooks, API requests and pull requests were back online, but issues with Copilot and the GitHub website remained as of 3:05 p.m. ET. The company didn’t declare the incident resolved until 5:15 p.m. ET.
It is not yet public what caused the outage. GitHub said it would share a “detailed root cause analysis” as soon as it has one.
This is at least the second major outage to hit a Microsoft platform in recent weeks. Many Xbox services were knocked offline for several hours late last month.
