IT Support During Winter 2024 Energy Curtailment

by

Due to the Winter Holiday, Energy Curtailment, and New Year’s Holidays, the Berkeley campus is officially closed for the period Tuesday, December 24 to Wednesday, January 1, reopening on Thursday, January 2, 2024. Additionally, much of campus is on reduced support for January 2-3.

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. You may wish to turn off any workstations or printers in your office, to help with energy savings.

The IRIS Helpdesk office will be closed Monday, December 23 through Friday, January 3, re-opening on Monday, January 6. If you need assistance between January 2-3, 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 at least January 2.

Requests for network support or new IRIS accounts that are received after noon Tuesday, December 17 may not be processed until January 6, 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 at least January 2.

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

Research / Staff Computing Environment: help@eecs

Happy Holidays!

DNS disruption for eecs.berkeley.edu, Nov 19

by

Tuesday afternoon and evening, November 19, we had a disruption of DNS resolution for the eecs.berkeley.edu domain on the campus nameservers. This meant that many systems outside of the EECS network were temporarily unable to resolve *.eecs.berkeley.edu hostnames — so people may have been temporarily unable to reach EECS websites or deliver email to some @eecs.berkeley.edu addresses.

New DNS Nameserver: themis.eecs

by

System administrators in EECS may be familiar with our DNS nameservers cronus and rhea. We now have a new nameserver, physically located in Cory Hall, named themis. If your systems are typical DHCP clients, or you don’t use the EECS wired network, then you should have nothing to change.

We are planning to replace and retire rhea according to the following schedule:

  • Thu Oct 15 — We will update our DHCP configuration, telling Cory Hall DHCP clients to use themis and cronus, and telling other DHCP clients to use cronus and themis.
  • November/December — We will monitor any continued usage of rhea for DNS, and periodically alert system administrators so they can update their systems to use themis instead.
  • early January — We will retire rhea, but will point its name and IP address at cronus.
