Soda 2F Network Interruption, 9/18 10:41 AM

September 18, 2025 by Derek Calderon

Networks on the second floor of Soda Hall were unavailable for approximately 5-10 minutes today beginning at 10:41 AM. This occurred due to a switch crash during troubleshooting a memory leak.

The network is now stable, but the memory leak issue still exists and requires further network disruption to resolve. We will be attempting to address this during tonight’s already-scheduled Soda Hall electrical shutdown.

Please contact us at help@eecs.berkeley.edu if you have any questions.

Network Instability, 8/31 9PM – 9/1 2AM

September 1, 2025 by Derek Calderon

Portions of the EECS and campus networks experienced instability last night between 9PM and 2AM due to DDoS-like traffic directed at a system on the EECS network. This ended without intervention from network staff; we are investigating and remaining on standby in case this reoccurs.

Please contact us at help@eecs.berkeley.edu if you have any questions or notice any issues.

Jacobs Hall Network Maintenance, Tue. 8/12 10PM – Wed. 8/13 7:30AM

August 8, 2025 by Derek Calderon

We will be performing Jacobs Hall network maintenance overnight from Tuesday, August 12th at 10PM to Wednesday, August 13th at 7:30AM. This maintenance is to replace the existing end-of-life router and switches with newer campus standard devices.

All wired and wireless networks in Jacobs Hall will be unavailable between 10PM Tuesday night and 7:30AM Wednesday morning. We expect all networks to be back online by 7:30AM.

Update: This work has been completed. Please contact us at help@eecs.berkeley.edu if you notice any network issues.

POSTPONED: Jacobs Hall Network Maintenance, Tues. Aug. 5 6AM

July 31, 2025 by Derek Calderon

At 6AM on Tuesday, August 5th, we will be migrating the first set of Jacobs Hall subnet gateways to new router hardware. This is being done because the current hardware is end-of-life, and also as part of a project to refresh Jacobs Hall networks to the current campus standard.

The following networks will be affected:
– Jacobs Hall general-use wired network (169.229.62.0/24)
– Jacobs Hall wireless networks

During this maintenance, the networks above will be unavailable for a period of time. We expect all work to be complete by 7AM.

Update 8/4: We are postponing this maintenance due to ongoing troubleshooting of a fiber link issue. A new announcement will be made when this work is re-scheduled. Please contact us at help@eecs.berkeley.edu with any questions.

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 Hall Network Outage, Tues. 2/18

February 18, 2025 by Derek Calderon

Cory Hall networks were unstable today between approx. 9:25AM – 11:00AM due to an apparent misbehaving end-user device on the 4th floor. We have temporarily removed this device from the network and all networks are stable at this time.

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.
