I rarely get 90k. In fact, the last time it had happened to me was around the 2.3 patch (which was taken care of by a maintenance).

Now Saturday I did have some lag issues, but I was able to determine that was because I had a Twitch.tv broadcaster on in the background.

But there still remains connection issues between ISPs and the data center in Montreal. And, while I've had Comcast & SE tell me it's not their end, I've come to the conclusion that it's in between and out of their hands, and it's that L3 company (that has a notorious reputation).
