Outage Description

Beginning at 2:00 a.m. on Saturday, October 24, 2009, nearly all University of Minnesota IT systems and applications will be unavailable for use. The outage of University services will also affect services provided by CFANS (see below). Some applications are scheduled to begin coming back online on Sunday, October 25, at approximately 1 a.m. All applications supported by the Office of Information Technology (OIT) are expected to be restored to service by 7:00 a.m. on October 25, and will become available on their normal schedule. The Outage Information webpage will be continually updated as they plan for and execute this outage.

Affected University Services

For a complete list, scroll down to the second half of the Outage Information webpage.

OIT has created the lists of which applications will be available during this outage and which will not. For the status of individual applications during the outage (between 2:00 a.m. on Saturday, October 24, and 7:00 a.m. on Sunday, October 25), visit the system status page. If an application is missing from this list, e-mail oca@umn.edu.

  Top Applications

Affected CFANS Services

  • Student Computer Labs
  • Active directory file shares
  • Linux Web Hosts
  • Urban Planet Web Hosts
  • SQL (college databases) Server

Process

A detailed description of the process is available at the Outage Information webpage.

During the outage, you can visit the Outage Information webpage for up-to-date information about the progress of the construction and system restart activities. In addition, the System Status page will be updated throughout the weekend to reflect the status of individual applications.

Explanation

This outage is being scheduled so that OIT can increase the amount of utility and emergency power to its primary data center, which is located in the West Bank Office Building (WBOB). This will allow OIT to increase the reliability, availability, and capacity of this data center.

If we have an event causing the loss of all power (i.e., both utility and generator backup power) in the WBOB Data Center, OIT currently does not have the capability to provide uninterrupted availability of Enterprise and University-wide Applications and many Departmental Applications. By upgrading the power system in this data center, OIT will be better able to support the applications and systems that reside there with decreased risk for unscheduled interruption to service.
