- Cloudflare's core data centers experienced a major boot delay issue after a firmware update.
- The problem stemmed from a linear search through network boot interfaces causing timeouts.
- By declaring the boot interface order early, boot times were reduced from hours to minutes.
- Collaboration with vendors and automation tools like iPXE helped solve the issue.
