I encourage the campus community to plan ahead:

  • charge cell phones before the outages,

  • carry a flashlight,

  • do not perform experiments or other work that rely on consistent power, etc.

  • work under the assumption that electrical power will be unavailable during the times noted.


Managers and supervisors have the responsibility for providing direction to employees, students, and volunteers, including operational decision-making. In the event of a power outage, they are responsible for employee safety and for the implementation of all related business continuity actions. Managers are asked to prepare and address any questions that individuals under their supervision may have. Please read this detailed information closely and work to ensure readiness.


Facilities information

  1. Emergency power – The standard emergency power supply for the campus, inclusive of emergency lighting, will be operable during the scheduled outage.

  2. Lighting – Managers should ensure that there is adequate lighting to support a safe workplace.  If a workplace does not have enough light to work, please reassign the employee workspace.  It’s also best to ensure that employees and offices have flashlights on hand.

  3. Elevators and accessibility – Building coordinators, divisional facilities staff, building managers, or supervisors will need to post signage at all floors indicating they should not be used during the outage period. Please print the attached signage pdf and assign the posting to a specific person. Use of the elevators during this time could result in entrapment within the elevators requiring a fire department response. Anyone needing an elevator to access their place of work or general campus activity should consult with their supervisor for alternative accessibility options and work locations for the time of the outage.

  4. Dining—Cowell/Stevenson Dining Hall will be closed during the outage.


Communications information

If the impacts go beyond the scheduled time, additional information will be posted


In addition to updating the webpage as information warrants, the Public Information Office will:

  1. Record information on the campus's communications hotline, 459-INFO (831-459-4636).

  2. Relay information on a regular basis to KZSC Radio (88.1 FM) for broadcast.

  3. Share information via Twitter,


Technology information

All campus services hosted in the Data Center will remain operational. Campus websites, digital and analog telephones, 911, the two-way radio systems, and non-cellular Blue Light phones will also be operational.


Please note the following may experience service interruptions:

  1. Network service in many campus buildings will be disrupted.

  2. Wireless connectivity and VoIP phones in buildings without backup generators will experience outages after batteries powering their serving switches run down.

  3. Campus cellular phone service will have limited coverage.

  4. Blue Light emergency phones that rely on cellular connectivity may be impacted. The locations of these phones are as follows:

    1. College 8 -- Footpath between College 8 and Oakes College

    2. Cowell Service Road, near Cowell Apts 3

    3. Grad Student Housing to Porter footpath (behind bldg 7736)

    4. Hagar at Steinhart Bus Stop,by Baytree Bookstore

    5. Hahn Parking Lot

    6. North Remote Parking

    7. Village entrance (not at bus stop)

  5. Research clusters hosted in the Data Center will be shut down.

  6. MyUCSC – although applications housed in the campus Data Center will remain fully functional during the outage, individuals working on campus should be prepared for building network outages which could disrupt connections to campus systems. Faculty especially should take precautions if entering grades via MyUCSC from their office or any campus building during the outage period, as a sudden network outage could result in lost work. Precautions include saving often, working from a non-campus location, or refraining from entering grades (or performing other critical systems-related work) during the outage window.


Emergency services

All campus emergency services will be operational including UCSC PD, dispatch and Santa Cruz Fire.  Per standard protocols, emergency response needs should be obtained via 9-1-1. Please do not contact dispatch for general outage questions or issues. These concerns should be directed to campus managers and supervisors.


Additional resources

The campus police department and Office of Emergency Services have multiple resources available on their websites. Emergency preparedness, training resources, and contacts:


If you have questions, please consult with your direct supervisor or department manager.
