I noticed this morning the ventrilo voice chat server is down. It is at the server end and they are migrating the service to a new server. Here is the message from the ventrilo people:
We expect services to be interrupted for a few minutes while we migrate your services to upgraded hardware.
Because of the nature of the event we expect the maintenance event to take the full four hours however each customer should only be affected for 10-20 minutes while their services are migrated.
