Cloudflare cuts core server boot time from hours to minutes

Cloudflare slashed the boot time of its core servers — the centralized bare-metal machines behind its control plane — from roughly four hours down to minutes. The fix isolates the minimal "fast path" needed to reach production from the full boot sequence, so a server returns to service quickly after a restart. Why this matters for us: faster recovery on Cloudflare's core infrastructure means shorter outages for the millions of small businesses and independent developers who rely on it for security and performance.
