It's been weirdly consistent. Last three nights at 9pm CDT like clockwork. Game is fine, clock strikes 9, game is no longer fine.

US, Chicago, Comcast, Primal DC.

The game becomes actually unplayable. Not acceptable. Oh and pathping doesn't agree that this is a Comcast problem. My latency actually triples the very instant I leave Comcast's network. Note please that I'm perfectly happy to blame Comcast for everything from internet lag to hair loss, but I don't think this is them.
