We've had some problems with the mumble server recently. So I've purchased a dedicated server through another company for a year. The new mumble info is:

Address: crow.mumbleboxes.com
Port: 36110
PW: ASCPW#3

We are all on the "Sanctum of Rall" server in Guild Wars 2. The guild name is, of course, ASC. Look for any of us on Steam or otherwise to give you an invite!
