Evolution of GitHub's data centers

This post details the evolution of GitHub's physical infrastructure, introducing a hub-and-spoke design with four facilities: two Points of Presence (POPs) for networking and two data centers for storage and compute. It describes the homogenous cabinet types, structured cabling for simplified capacity expansion, and the role of gPanel in hardware management, including automated provisioning and validation. The post also highlights the use of cabinet integrators for rack and stack, cabling, and logistics, enabling hardware to be made available for provisioning on the same day cabinets are powered up.
