Has this happened to anyone else in the last couple of weeks?
Both weeks the downtime was scheduled to begin at 5 and at that time others seem to be unable to login anymore. Tonight my second account couldn't even get it to accept my password - I just got the unable to to connect message - but characters that are online stay online. I was just finally DCd a few minutes ago (7ish) and the last time I had checked there were only seven horde players online on my server.
So my tip, if you want to keep playing for a couple of extra hours - get logged on before 5 and don't log off! Not even sure if everyone else was booted or if I just DCd. I got the idea to go looking for the TLPD in Storm Peaks and I thought CRZ might have DCd me.
