At midday UK time (12 GMT) today our network team activated a feature called HTTP/2 (or h2 for short) for our Community website. You might notice pages loading slightly faster than they did before. There shouldn't be any other differences. Hit us up in the comments if you spot anything odd happening.


Technical overview


HTTP/2 is major revision of the HTTP network protocol used by the World Wide Web which received major browser support from 2015 onward.


Instead of opening up 1 socket connection per requested asset (with a typical Community page containing 30 resources over and another 30 on, it opens 1 socket per domain and multiplexes all the assets through it, greatly reducing the connection overhead.



Browser Support


Most modern browsers support HTTP/2, and if they don't, they'll just use a HTTP/1.1 connection, which makes this change a no-brainer.
