The University data center at the West Bank Office Building will be powered down from 6 a.m. Saturday, January 4th, until 6 a.m. Sunday, January 5th, for annual maintenance. A complete list of affected services is found on the OIT System Outage and Maintenance Status page. Updates will be available on the University's system status page, and on social media outlets Twitter @UMN_IT and the University of Minnesota Information Technology Facebook page during the service interruption period.
CLA system administrators will shut down CLA systems before power is cut, beginning at 10 p.m. on Friday, January 3rd. All affected services are expected to be restored by 6 p.m. on Sunday, January 5th.
CLA system engineers will also take advantage of this outage by carrying out routine maintenance tasks including security patching and equipment upgrades.
What is a "system maintenance window"?
In order to correct a technical issue, install a security patch, or upgrade server hardware, central OIT or CLA-OIT must occasionally disrupt normal networked services. Whenever possible, we plan such service outages in advance during times that minimize the disruption to our students, staff, and faculty.
Can I work during the maintenance window?
In general, CLA-OIT recommends that you avoid using the affected services during the maintenance window. Systems may be available during the maintenance window, but they can and will be shut down without warning and may be unavailable for hours at a time. Please use only at your own risk.
Can't this be done without disrupting service?
Certain tasks require server reboots and/or physically unplugging electricity. We do our best to group these tasks together to minimize the number of outages we schedule each year--which is generally less than five.
Can you reschedule this window to a more convenient time?
As determined by consensus of the UMN IT community representing each college and administrative unit's technology needs, the first full weekend in January following the New Year holiday has been established as the regular maintenance shutdown weekend each year. The work is being planned through coordinated efforts with the UMN Information Technology Change Approval Board
