The primary Soda Hall machine room lost power around 3:10pm Dec 1. Most IRIS services were impacted. Power has been restored and most services have recovered.

This article will soon be updated with details on the cause of the outage once our technicians have finished restoring services.

UPDATE

[2017-12-01 16:04:42 | Derek Calderon]

The breaker serving our server room was blown, during a supposedly normal repair procedure on the UPS which failed Tuesday night.

Power, network, and services have been restored and the vendor technician responsible has finished and departed from the machine room.

We will coordinate with EECS Facilities to determine the correct repair path going forward, and will be questioning the vendor as to how a standard procedure could cause such a drastic failure. For the mean time we are again without battery backup in our main server room.
