CSE File Server Reboot Tonight 9/15/08 at 11:30PM

We will continue to work with RedHat to resolve the matter with the newer kernal.

HVAC Preventive Maintenance Schedule for June 29, 2008
OPP will be performing preventive maintenance procedures on all of the air handlers in the IST Building between 2PM and 10PM today, June 29. To lessen the overall impact, OPP will rotate through the air handlers one-at-a-time. You may notice some warm-up in your offices but the effect should last less than an hour. As always, IT will closely monitor the conditions in the Computing Machine Room. Should the temperatures rise above a safe threshold, we will preemptively shut down non-critical systems until CMR temperatures drop. -jd
