GitHub is having some major issues right now…

TL;DR

GitHub's uptime collapsed to 86% in April 2026, with lost pull requests, search outages, and a critical RCE vulnerability driving developers away.

Key Points

• 1.GitHub's reliability has deteriorated sharply in 2026. Third-party monitoring shows uptime dipped below 90% in 2025 and hit ~86% in April 2026, while GitHub's own status page falsely reports 99%+ uptime across all services.
• 2.Three major incidents struck within one week. On April 23rd, 292 pull requests were unmerged across 658 repos; on April 27th, a botnet took down GitHub search for hours; on April 28th, a critical RCE vulnerability was disclosed allowing code execution via git push.
• 3.Mitchell Hashimoto's departure was the tipping point. The creator of Vagrant and Terraform, GitHub user #1,299 since 2008, publicly announced he was moving his 50,000-star project Ghosty off GitHub after logging outages blocking his work nearly every day for a month.
• 4.AI agents are a root cause of the strain. GitHub's own CTO admitted that agentic development workflows have accelerated sharply since 2025, meaning AI agents are hammering infrastructure at scale — alternatives like GitLab, Codeberg, and SourceHut stand ready to benefit.
