Please have a look at the data before writing such statement. In the latest CloudFlare article [1] about it (Feb 2016), they concluded that only 52.93% of their users are connecting over HTTP/2.

Which statement? All major browsers can work with it. Apache and nginx, at least can also work with it (encompassing 85% of all internet servers).

That users aren't connecting to http/2 web sites is no indicator that http/2 is not available.

Like any Internet Explorer on any non-Windows 10 systems?

If 47% of all CloudFlare users are not connecting via HTTP/2 (even though it is supported server side), I believe it means that those users do not have client side support (or are behind a proxy, etc. which doesn't allow it).

At the end, if someone is thinking about making a website which would be much slower for non-HTTP/2 users then right now it means around 47% of their users.

I said "all current, major browsers" in my original post. IE is not Microsoft's current browser. In addition, not all web sites are serving via http/2 and that web sites aren't using http/2 is no fault of the browser or the user.

The conclusion of that blog post was that you should enable HTTP2 on your site.

Nginx and other servers handle both automatically no?

Yes, but the problem is on the client (browser) side.

I am not aware of any current major browser that does not support http/2. http://caniuse.com/#search=http%2F2
