Hi, Sean. I had precisely this experience, mostly noticed just in the past day or so. I assumed it was an effect of the firewall/NAT setup that my corporate IT network has implemented, because it often is a culprit in these kind of situations... But noticing that it was only for QUIC connections to Google (I likewise use Apps hosted email) I just turned off QUIC in Chrome and the problem went away.
I have no real insight about the issue beyond that. Except to say that the packets captures I performed were not very useful to me, personally, because encrypted QUIC traffic isn't very revealing in Wireshark. :) Though I may simply be missing some clue and/or skill in making sense of it. I guess I'm glad to hear that others such as yourself are seeing the same problem. Because now I don't have to harass my corporate IT dept. Instead we can look forward to speculation about Google, QUIC adoption in the near future, etc. Cheers, -Benson On Wednesday, September 23, 2015, Sean Hunter <jamesb2...@gmail.com> wrote: > Hi all, > > I work for a 2500 user university and we've seen some odd behavior > recently. 2-4 weeks ago we started seeing Google searches that would fail > for ~2 minutes, or disconnects in Gmail briefly.
