I'm getting it too. I think it's a pretty safe bet this is a server traffic related issue. -shrug- We all knew this was going to happen. I guess it shows the wisdom of doing the roll-out slowly over a couple of days.
I just hope this is not an indication of things to come tomorrow. Today it's okay. There's no rush since you have all day to accomplish the one thing you need to accompish with no time-critical element. But tomorrow...
My guess is that Jooky is disabling the login server database on purpose to limit the amount of people in game at one time until he sorts these lag issues.
