IT Support During Winter 2023 Energy Curtailment

December 8, 2023 by Lars Rohrbach

Due to the Winter Holiday, Energy Curtailment, and New Year’s Holidays, the Berkeley campus is officially closed for the period Monday, December 25 to Tuesday, January 2, reopening on Wednesday, January 3, 2024. 

All departmental computing servers will remain on and should be available during the break, but there will be no staff on site to provide any computing support or handle any requests. Automatic monitoring systems will alert staff to critical infrastructure problems, and any such problems will be dealt with on a best-effort basis.

The IRIS Helpdesk office will be closed Wednesday, December 20 through Friday, January 5, re-opening on January 8. Helpdesk staff will be operating remotely December 20-23, and January 3-5. If you need on-site assistance between December 20-23 or January 3-5, please email help@eecs, and we may be able to schedule an appointment with you. Problem reports can be left on the Helpdesk voice mail (510-642-7777) or emailed to help@eecs during the campus closure period, but staff may not receive or reply to these messages until January 3.

Requests for new IRIS accounts that are received after 5pm December 15 may not be processed until January 3, 2024. Requests for network support that are received after 5pm December 20 may not be processed until January 3, 2024.

During the break, Instructional labs will be locked, but the main servers will remain online (for details, see the Instructional website). Instructional support staff will occasionally monitor inst@eecs email over the break. Please be aware, though, that staff may not be able to respond or reply to messages until January 3.

Computing support staff will be monitoring their email when possible, so please use standard email addresses to report any urgent problems. As a reminder:

Instructional Computing Environment: inst@eecs

Soda Hall Power Outage on January 4, 2024

November 16, 2023 by Lars Rohrbach

To accommodate the installation of new circuit breakers and PDU (Power Distribution Unit) connections, all electrical power to the 2nd and 4th floors of Soda Hall will be shutdown during the day of Thursday, January 4, 2024. Critical systems will be down from 6am until perhaps 5pm.
