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

Some 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.

Not just tls but generally tcp will slowstart faster on lower rtt connection (and edge can keep origin connection always open so it stays “warm”)
