GitHub Plans 4 Million CPU Cores as AI Agent Traffic Surges

Oct 29, 2026
GitHub plans to add four million CPU cores and 160 petabytes of storage after AI agents drove a sharp increase in code commits and contributed to service outages.

GitHub plans to add four million CPU cores and 160 petabytes of fast storage to handle rising demand from AI coding agents, according to The Register. The infrastructure roadmap also includes more capacity for GitHub Actions.

GitHub recorded 7.4 billion code commits in September 2026, five times the total from a year earlier. The increase contributed to outages and other availability problems throughout 2026. On May 7, availability for the preceding 90 days fell to about 84 percent, based on data reconstructed from GitHub's status page.

The company is separating compute and storage in an architecture designed to support 35 times more throughput. It is also moving its systems to multiple Azure regions and expects to complete that migration in early 2027.

At the same Universe event, GitHub made Copilot Fusion generally available.
