Recent trouble with QUIC?

Fri Sep 25 22:52:17 UTC 2015

a) yes, 56,000 students and any on Chrome failed. I immediately blocked
quic and told users to restart Chrome. Luckily the fallback to good ol' tcp
saved the day.

b) I had this issue a few months ago and it subsided quickly

Google reports it's an issue in this version of Chrome and the next version
will have a little smarts to automatically re initiate the connection with
TCP automatically without having to disable quic.
