GitHub availability stays strained under AI coding traffic

Category: Infrastructure
Status: developing
Sources: The Register, GitHub Status
Summary: GitHub continues to log service-degrading incidents as AI coding agents drive a traffic surge. The Register reports nine such incidents in May 2026 and availability below the 99.9 percent enterprise threshold, with about 275 million commits per week and roughly 40 percent of monolith traffic on Azure by May, targeting near 50 percent by July; multiple outlets report Microsoft added AWS capacity for overflow. GitHub Status recorded further degradations on 2026-06-17 (Copilot code completions and webhook deliveries). GitHub and Microsoft have not published a single primary statement consolidating the figures.
Why it matters: GitHub is critical developer infrastructure, and a sustained availability shortfall driven by agent traffic affects CI, releases, and enterprise SLAs across the ecosystem.
Follow-up: Watch for an official GitHub availability report or Microsoft statement confirming the AWS arrangement and Azure migration milestones.
