AT A GLANCE

WHAT: Davis Campus Data Center service interruption, putting a hold on all campus e-mail and affecting most of the other computing services that are hosted by the center. The �ٺ���Ƶ Health System will not be affected.

WHY: Facilities Management will shut off the power while campus technicians upgrade the center’s electrical system, adding capacity for new research computing clusters and departmental administrative servers. The work will be done with the power off, rather than “live,” for the safety of technicians and to safeguard the center and its equipment.

WHEN: Starts at 7 a.m. Sunday, Dec. 26, and could last up to 48 hours, until 7 a.m. Tuesday, Dec. 28 — although officials are optimistic that the work will take far less time. Officials picked this time period because students and many faculty and staff members will be on winter break.

UP OR DOWN?

Here are some of the significant services that will be down:

• All campus e-mail — Incoming and outgoing e-mail will be stored during the service interruption, then will make its way normally through the Data Center — which routes most campus e-mail, even if your e-mail server is outside the Data Center.

• DaFIS — �ٺ���Ƶ Financial Information System

• Banner and SISWeb — Student information systems

• MyUCDavis — Web portal

• SmartSite — Course management and collaboration system

• Online grade submission — The services provided through SmartSite and the E-grading site ()

• Department servers and research computing clusters that are hosted by the center

• Wireless networks — Moobilenet and Moobilenetx. (Wired connections will be working.)

Here are some of the websites and Web services that will be up and running:

• — To be hosted temporarily by the �ٺ���Ƶ Health System, which will not be affected by the electrical project at the Davis Campus Data Center. A message on the home page will alert people to the service interruption and direct them to the Campus Network and Server Status page for more information.

• — This page will display complete information on the service interruption.

• Central Authentication Service, or CAS — An important service for people wishing to access secure online services on servers that are housed outside the Data Center but which still require users to enter Kerberos ID.

• Domain Name Service — This is the system that turns URLs into IP addresses and gets people where they want to go on the Internet.

Also, �ٺ���Ƶ websites and Web services will still work if they are on servers outside the Data Center. For example:

• and the sites, which are hosted by University Relations. People who make gifts will see a confirmation notice on their monitors, but the follow-up confirmation e-mails will be delayed during the Data Center service interruption.

• Environmental and equipment alarms, for the safety of research animals, also will be unaffected — as these alarms run through servers that are housed at a satellite location, not in the Data Center.
