EECS Network Maintenance, Wed. Mar. 26

March 24, 2025 by Derek Calderon

We will be performing various network maintenance activities throughout the day on Wednesday, March 26th during the previously announced Soda Hall 2nd floor power shutdown. We expect that most of our work will not affect wired and wi-fi network service, however there will be some brief outages as described below.

Between 12PM and 1PM on the 26th, the areas listed below will experience at least one interruption to network connectivity. We expect most of these interruptions to be under one minute in length, but some wi-fi service may be unavailable for 5-10 minutes.

  • BWRC (wired and wi-fi)
  • BiD in HMMB (EECS wired)
  • Soda Hall all floors (wi-fi)
  • Soda Hall 4F north side, 5F-7F (wired and wi-fi)

Update 15:44: This work has been completed and all networks are online. Please contact us at help@eecs.berkeley.edu if you notice any issues.

Cory 3F Network Offline, Thursday 11/14 early AM

November 12, 2024 by Derek Calderon

On Thursday, November 14th, between 6:30 and 9:45 AM, Cory Hall third floor wired and wireless networks will be offline due to electrical work being performed at the main service panel. Facilities is performing this work in order to restore electrical power to the Cory Hall Helpdesk.

Facilities is reporting that the west side of the third floor (which includes the network closet) will be without power from 6:30 – 9:30 AM. The network devices, particularly the wi-fi APs, will need some time to boot up after power is restored. We typically expect network connectivity to be restored within 10-20 minutes after power returns to the network closet.

Update 11/14 9:36AM: This work was apparently completed without any interruption to the network. Please contact help@eecs.berkeley.edu if you have any questions.
