Yeah, 5am EST is the latest advised time.
Don't totally hate the downtime because I have no shortage of singleplayer games, but I'm not pleased with the misinformation that users who logged in during the pre-maintenance timeframe would be able to continue online access over the course of maintenance. Having been online extensively during the 15th and 16th, I can attest that the advisory in that regard is not true.
I think matience may be done. though I was never bothered by it. I played right through it, never signed our or nothin! I could play online except for Starhawk... For some reason Starhawk servers were down during the matience I guess but I could play Bf3 though.
