Last evening about 21:26 there was a power failure in the main EECS server room in Soda Hall. The UPS held up some systems until about 22:00 at which time staff shut the room down completely. Many EECS services were disrupted as a result. The problem was found to be in the UPS which fried the high voltage output terminal block. The terminal block was bypassed and the UPS has been removed from service until further notice. Most EECS computing services have been restored as of 03:15 this morning with the exception of the IRIS web server, which was restored around 10:15am Sunday.
Thanks to the staff who came in early Sunday morning to deal with this issue.
