GitHub reports degraded performance, pauses Central US rollout during Azure migration
Why it matters for readers: It explains why GitHub performance may vary and what the company is changing to improve it.
- Two incidents in September caused degraded performance across GitHub services, prompting further reliability work.1
- GitHub moved many workloads to Microsoft Azure and by October 7 had deployed 120 of 160 production services in Central US.1
- By October 7 Azure handled 65.4% of core read traffic, 48.3% of Git read traffic, and 80.2% of stream-processing traffic for GitHub.1
- A pause on Central US deployments and traffic increases began September 11 due to uneven availability-zone capacity and resumed temporarily on September 18, but durable capacity work continues.1
- GitHub missed its aggressive September 30 goal to complete all Central US deployments and an automated failover disconnected Central US during a planned database failover.1
