Hello, we have a large amount of Google Chrome users. I am starting to hear the odd complaint about slow connections to some sites on the internet. As a test I disabled the QUIC protocol (UDP 443) in the web browsers at one site, and the complaints stopped. In addition we also block QUIC on our firewall.
So it would seem that browsers were failing to communicate via QUIC and then either stalling or taking too long to revert to TCP 443.
Are any other of you network engineers seeing the same sort of problem ? - I was considering disabling QUIC in all Chrome browsers company-wide.
