net/http: https://http2.golang.org/reqinfo does not work anymore

[tranb3r]

The request https://http2.golang.org/reqinfo does not seem to work anymore.
I've tested several browsers, operating systems, dns.
Is it still available ? Any alternative solution ?

Is it still available?

Likely not; the http2 demo server was turned off. See #49301.

Closing here, but feel free to post in #49301 if you have something to add.
