GitHub Rebuilds Git Storage as AI Agents Drive Surging Commit and Push Volumes

GitHub has published a blog post describing a rebuild of the storage layer beneath all its Git repositories, driven by the growth of AI agents. In September, developers and agents made 7.38 billion commits, more than five times the previous year, with pushes reaching 3.35 billion a month. The current Spokes system keeps a full copy of each repository on five file servers and requires a majority to agree on every ref update, so adding read capacity by adding copies slows down writes. GitHub plans to separate data safety from traffic serving, running heavy push steps in parallel so only the small ref-update step is serialized. This matters most for the main branch, where merges compete to update the same ref.
