Twitch rewrote their backend from Rails to Go. They also rewrote their frontend in React (previously Ember.js)[1] I know I've also seen a Twitch developer stream themselves benchmarking Rust + io_uring vs Go but I don't know if anything ever came of that. Discord rewrote at least one Go service in Rust. [2] Cloudflare made Pingora (Rust) to use instead of NGINX (C) though idk if that meets the rewrite criteria.
