One physical machine (vsp09) is down, bringing down all of its related VM's (vsp09*). We're working on it and hopefully will be able to get it back up today, unless there's a more serious issue.
UPDATE: The machine is now back up and the main CS (vsp09a) is running. We are keeping the other CS's down, since the other CS's are now obsolete and have been integrated into vsp09a.
