And now try to load the same website over HTTPS

I know some people who are experimenting with using shorter certificates, i.e. shorter certificate chains, to reduce traffic. If you're a large enough site, then you can save a ton of traffic every day.

Please though, for the love of dog, have your site serve a complete chain and don't have the browser or software stack do AIA chasing.

Yeah I think this computation doesn’t work anymore once you factor in the tls handshake.

From TFA:

This hasn’t been the case since TLS1.3 (over 5 years ago) which reduced it to 1-RTT - or 0-RTT when keys are known (cached or preshared). Same with QUIC.
