GitHub unveils new Git storage architecture
The gist
GitHub detailed a new Git storage architecture it says hit 7,200 pushes per second in internal tests.
The rebuild targets AI agents pushing code around the clock, not just humans.
How it unfolded
- May 2026GitHub began developing the design called Rubicon after the initial Azure migration.
- Oct 28, 2026At GitHub Universe 2026, GitHub laid out its vision for GitHub as an end-to-end software delivery system, saying three principles guide the new Git architecture: simplify the primitives, decouple storage from compute, and minimize coordination.
- Nov 2, 2026A DEV Community attendee's write-up of GitHub Universe 2026, held at Fort Mason in San Francisco, reported April Leonard detailing the rebuild of GitHub's core Git storage subsystem.
