GitHub publishes Rubicon agent-scale Git storage architecture and limited private preview

On 5 November 2026 GitHub published an engineering account of its Rubicon Git storage architecture, decoupling repository objects from per-reference state for heavy parallel agent workloads. GitHub reports a 5,000 concurrent agent and 7,200 pushes/second INTERNAL stress test, and limited private preview rather than general availability. The technical publication and limited preview are the milestone; internal test capacity is not independently verified production performance or a broadly shipped feature.
