The computer that hosts the VDT web site and software caches  
(vdt.cs.wisc.edu) is having a disk problem and maintenance will be  
performed on it at 4:00pm Central Time today.
We hope that the maintenance will not cause downtime for the VDT web  
site, but it might. We apologize in advance for any inconvenience this  
might cause for you, and we'll get things back online as quickly as  
possible.
In the event that an interruption in service occurs for the VDT  
software cache, the OSG software cache will also be unavailable.
