Got as similar effect, just suddenly booted from server. I got the 'cannot connect to server; try again later message' then my play icon just greyed out. Time for a break.
Just calculated my 16 hours wait. Ironically it would be about the time I will be logging in tomorrow. After sleeping, doing the weekly shopping, putting in a few hours of work and getting lunch. LOL
