THE CRUNCH
GitHub is rebuilding the Git infrastructure behind its platform to cope with agentic software development, where AI agents commit and checkpoint after nearly every action and push latency becomes the limiting factor. The company says total Git activity more than doubled between September 2025 and August 2026, from 218.2 billion to 473.3 billion events per month, and that developers and agents made 7.38 billion commits in September alone, more than five times the figure a year earlier.
The numbers behind the shift are stark. Monthly pushes grew 4.9x year over year to 3.35 billion, pull request merges reached nearly 4x their previous volume, and GitHub Actions ran 3.26 billion times in September, more than 4x as many as a year earlier. The busiest repository on the platform saw roughly a billion requests in August 2026, and CI systems cloning the same branch tip thousands of times per minute multiply every push into a flood of reads.
The current architecture stores every repository on several fileservers, five by default, with each replica participating in every write through a quorum-based protocol. That couples durability to scale: adding replicas to absorb read load makes writes slower, and losing quorum stops writes entirely. GitHub says the rebuild will separate durability from scale, and that the work will happen while the platform keeps running, with no maintenance window and no changes to how people build software.
