Pingora, the proxy that connects Cloudflare to the Internet
> When crashes do occur an engineer needs to spend time to diagnose how it happened and what caused it. Since Pingora's inception we’ve served a few hundred trillion requests and have yet to crash due to our service code.<p>> In fact, Pingora crashes are so rare we usually find unrelated issues when we do encounter one. Recently we discovered a kernel bug soon after our service started crashing. We've also discovered hardware issues on a few machines, in the past ruling out rare memory bugs caused by our software even after significant debugging was nearly impossible.<p>That's quite the endorsement of Rust. A lot of people focus on the fact that Rust can't absolutely guarantee freedom from crashes and memory safety issues. Which I think misses the point that this kind of experience of running high traffic Rust services in production for months almost without a single issue is <i>common</i> in practice.
