GitHub Uptime Hits 86% in April; Hashimoto Leaves Platform After 18 Years

GitHub's April 2026 uptime fell to approximately 86% according to third-party monitoring, against the platform's own status page reporting near-perfect availability. Three major incidents hit in one week: on April 23, Merge Queue silently un-merged 292 PRs across 658 repositories; on April 27, an Elasticsearch botnet attack downed search for hours; on April 28, a critical RCE vulnerability was disclosed on git push. GitHub's CTO attributed the degradation to "agentic development workflows accelerating sharply since 2025." Mitchell Hashimoto—user #1,299, on the platform 18 years—publicly left for Ghosty. Zig had already migrated.

Why It Matters

The CTO's admission that coding agents are overloading GitHub's infrastructure is the first official acknowledgement of a structural inflection; the platform hosting most of the world's open-source code is visibly struggling with the agent era it enabled.
