I've never had it so I couldn't log on at all, but over the past couple of days multiple times it has been sitting at the login screen for 30+ seconds saying connecting before it finally got trough. Usually its instantaneous, and others in a guild I'm in have experienced the same thing, so I think the login server or maybe the char server is having issues. A related issue is that a couple of times I've gotten DCed when switching characters over the past few days, which never happened before either.
My chars: TPC / Tjuven / Dansare / Sinne / Magiker / Byracka / Krigare / Andreas
