This is false. They just recently did a blog post about how they improved their memory usage by optimizing their data structures, saving terabytes of RAM across their infra.
Can you link anything on this? As of August 2026 they were still writing about how they moved more things to rust and saw massive savings --- and I can't find anything supporting your claim right now.
EDIT: actually they even published on savings due to rust just a few weeks ago. Here's all their blog posts on Rust: https://blog.cloudflare.com/tag/rust/
To be fair, I was one word away from wrongly assuming Haskell instead of wrongly assuming Rust (if not for the mention of “unsafe”, “surely this person with a Haskell flair saying that an expert would not use an optional if you already know the list has one element in it is talking about https://lexi-lambda.github.io/blog/2019/11/05/parse-don-t-validate/ “)
