Cloudflare FL2: Rust Rewrite Cuts Latency and Boosts CDN

🚀 Cloudflare announced FL2, a complete reimplementation of its FL request-processing layer using Rust and the Oxy framework. FL2 adopts strict modular phases, eliminates cross-language overhead, and supports graceful restarts with systemd socket activation and the Rust-based shellflip coordinator. Internal and third-party tests show FL2 reduces median response times by ~10 ms and delivers a ~25% performance improvement; staged rollouts, automated testing, and fallbacks to FL1 enabled safe incremental migration.
