GitHub, the Microsoft-owned code-sharing platform with 225 million users, was down for more than three hours Monday morning, disrupting software development work around the world.
The issue started at 6:40 a.m. Pacific. Within an hour and a half, nearly every part of the service was broken or slowed, including the GitHub website, tools for reviewing and merging code, the automated systems that test and ship software, and the GitHub Copilot AI coding assistant.
GitHub said on its status page that it found the source of the problem shortly after 9:30 a.m. and by 10 a.m. had the outage under control, with services recovering. Copilot remained listed as an active incident and GitHub said it was still monitoring things overall for stability.
As of publication time, the company hadn’t detailed the cause of the issue.
GitHub has been struggling for many months with the surge of AI-driven coding. GitHub CTO Vladimir Fedorov wrote in April that the company set out last fall to expand its capacity tenfold, then concluded by February that it needed to build for 30 times its current scale.
In June, a Microsoft spokesperson told Business Insider that the spike in AI agent development had tested GitHub’s infrastructure limits, and said the company was accelerating GitHub’s move onto Azure while pursuing a multi-cloud strategy. BI reported that the strategy includes renting capacity from Amazon Web Services, Microsoft’s biggest cloud rival.
