Ah, the TLS shortening aspect of a CDN is something that seems obvious in hindsight but I'd never really thought about it. Thanks!

- dilyevsky 5y agoNot just tls but generally tcp will slowstart faster on lower rtt connection (and edge can keep origin connection always open so it stays “warm”)
- hinkley 5y agoSome of the HTTP/2 and HTTP3 design choices are seen as trying to solve this problem another way. If a round trip to New York is too long, then twenty of them is way worse. So I can either do 20 round trips to Nevada, which does <20 round trips to Chicago, which does <<20 round trips to New York. Or, I can do some more cleverness with transport and session bootstrapping and end up with 14 round trips to New York.
