Upgrading dhcp.eecs Friday, July 5

June 26, 2024 by Lars Rohrbach

On Friday, July 5, from about noon to 2pm, we will be performing an OS upgrade for dhcp.eecs.

During this time, DHCP service will be handled by our backup DHCP server, so there should be no significant interruption of service — but no new DHCP updates will be processed (i.e. new system network registrations will not become effective until after the upgrade is complete).

Unplanned East Campus Power Outage

May 22, 2024 by Lars Rohrbach

Just before 6:30pm, the campus experienced a wide-spread power outage. Most of the east side of campus remains without power at the time of this writing. There is currently no estimate for when power will be restored.

IRIS services in Soda and Cory will be either shut down imminently, or will soon become unavailable, as UPS power is used up. Once power is safely restored to campus, we will work to bring services back online to the best of our abilities.
