GitHub details new Git storage architecture for the agent era

Summary

GitHub has published the internals of its new Git storage architecture, code-named Rubicon, designed so thousands of agents can work on a single repository at once. In internal testing it supported 5,000 concurrent agents on one repository and 7,200 pushes per second while serving reads at consistently low latency. Git objects live in Azure Blob Storage while reference updates go through a separate replicated log service called Ref-CAS, decoupling storage from compute; developers keep using Git exactly as before.

Why it matters for our work

As coding agents multiply, repository read and write traffic explodes, so collaboration infrastructure is being redesigned first. This is the physical groundwork for millions of developers building with agents.
