I am (and a few other people I know do) getting crippling login/connectivity issues since the Account System maintenance started.

I was unable to login at all during it, and after it, I am getting a slew of varying errors (error 200, the "username or password may be incorrect or inactive at this time", "lost connection to the lobby", etc, changing randomly) and even when I manage login, the connection gets lost after a short while.

Same happens to at least two other people I talked to.

What's going on there?
