Nothing shown in the game or on the server list page.. :'(
I just noticed that too, but hope it's not a sign of no activity. It's ironic I've been slammed busy for months unable to get online for fun, and now I have time only to find no server active. :'( I concur...
I've restarted the server, it seems to be back up now.
If this happens again, send me an email or PM, I will notice that quicker than a forum post (I don't always check the forum that regularly).
