How we reduced core unit boot time from hours to minutes
Cloudflare identified a UEFI firmware flaw in linear network boot interface search, reducing core server reboot time from 4 hours to minutes across nearly 2,000 Gen12 units by skipping invalid IPv4 HTTPS/iPXE attempts and directly using IPv6 HTTPS boot.
入选理由:Cloudflare 的 Gen12 服务器在固件更新后因 UEFI 线性搜索所有网络启动接口导致单次重启耗时 20 分钟,累计达 4 小时。
