Cloudflare Outage Linked to Rust Code Rewrite from C

Crackling crust, pillowy middle. The kind of bagel that earns a second cup of coffee.
Summary
The article discusses Cloudflare's largest-ever outage, attributing it to a significant factor: code rewritten from C to Rust. The Rust-based code encountered an issue where it parsed only a fraction of a configuration file due to an upstream error making the config much larger than expected. The code used ".unwrap()" which caused a panic and crashed the entire program. The article frames this as validating criticisms from programmers who question Rust advocates' relentless promotion of the language for adoption.
Key quotes
· 3 pulledIn the chain of events that led to Cloudflare's largest ever outage, code they'd rewritten from C to Rust was significant factor.
Their Rust code parsed a fraction of the config, then did '.unwrap()' and panicked, crashing the entire program.
This validated a number of things that programmers say in response to Rust advocates who relentlessly badger people in pursuit of mindshare and adoption.
