As a network operator my goal was always to ensure customers receive the traffic they expected, high rates of UDP were often not what they wanted.
Well, I wouldn't say I *want* UDP traffic, but if everyone is bound and determined to send it to me for web / video traffic unless I block it, I suppose we should all work together to improve my (average v4 end-user) experience. I set up a rolling tcpdump to capture QUIC / HTTP/3 traffic. tcpdump -C 100 -w quic -W 100 -i eth1 'udp and port 443' I can make this dump available for inspection if (when) I organically experience the issue again. Is there anything else I can do to help Google or AT&T improve things? Any magic debugging I can turn on on the client side? Feel free to ping me off list... I don't particularly *want* to block or advocate blocking QUIC, but if I keep hitting the issue and can't help people troubleshoot, what other sane option have I? -- Dan
