I've noticed significant lag over the last month or so that didn't seem to be a thing before. I don't think I have played a Survival game in the last month that was not "Poor connection to host server". My guess is that Massive is shutting down servers as the Division 1 winds down, and they spin up for Div 2. They may be using some of them for Div 2 in house "Alpha" testing. Not sure, but that would be my guess.
