Autonomous hardware diagnostics and recovery at scale

What this post added

This post introduces 'Phoenix,' an autonomous diagnostics and recovery automation system for Cloudflare's global hardware infrastructure. Phoenix automates the detection, diagnosis, and re-provisioning of broken servers, significantly reducing manual effort and improving operational efficiency. It includes out-of-band connectivity checks, integrated node acceptance tests (INAT), and an 'Error Budget' concept to balance automation with empathy for potential recurring hardware failures.
