So cloudflare went down

Cloudflare experienced a major outage caused by their bot management system receiving over 200 feature flags instead of the expected 60. The service used Rust's unwrap method for error handling, which panicked when the pre-allocated memory limits were exceeded. The incident highlights the trade-offs between performance optimization through pre-allocation and robust error handling in high-traffic server environments. While some criticized Rust, the failure would likely have occurred regardless of language choice given the architectural constraints.
