Hey, sysadmins/dev-ops folks in my follows: How common is it for large network firewalls to block/otherwise not support HTTP/2? I know this sometimes happens—not only have I read about it, I've also had to live behind that sort of firewall before (sad times …)
Related: is there any other reason users wouldn't be getting HTTP/2 if I have everything set up right on my end? I know that browser support is pretty good these days.
