Past week+ yeah I've had odd packet drops and slingshots. I started to assume it was Comcast being Comcast or possibly another one of my lines or cables starting to fail (already have had two, lel) but if others might be getting it then maybe I can be a bit relieved.

There have been times that couple days before big patches people start to experience something. I'd say they probably do start tinkering in the server in preparation.
