Scheduled Outage: Friday, March 21, 2014

To make repairs on the chilled water system, the Physical Plant will be shutting down chilled water for several hours Friday morning, starting at about 7:00am.

Chilled water is essential for the correct operation of Biostatistics' main server room in the CSC. When the water stops flowing, the temperature shoots up to 100-110F in about 20-30 minutes.
