We had a brief partial outage to EECS networks this morning between 7:15-7:20 due to an unplanned device reboot during a troubleshooting procedure. All networks should be back online at this time. Please contact us at help@eecs.berkeley.edu if you notice any issues.

Cory 165 Network Maintenance, Wed. June 4th 10AM-12PM
On Wednesday, June 4th, between 10AM and 12PM, we will be replacing the Ethernet switches in the Cory 165 server room. The current switches have reached the end of their useful life, and with the newer hardware we can begin to provide some limited 10G connectivity.
All systems in Cory 165 will experience a brief interruption in network connectivity, typically less than one minute, as connections are moved to the new switches. No action should be necessary, but a reboot may help if you notice any issues afterwards.
Update 6/4 11:32: This work has been completed. Please contact us at help@eecs.berkeley.edu if you notice any ongoing issues.
EECS Network Maintenance, Wed. Mar. 26
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
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.
Please contact us at help@eecs.berkeley.edu if you notice any issues or have any questions.
Campus Network Instability, Fri. Feb 7
We have been experiencing campus-level network instability since sometime around midnight, which is affecting the EECS and BWRC networks. Network team is investigating and working with the vendor to restore full network connectivity.
Update 2/11 6:41AM: The campus network team resolved these issues late Friday evening and our monitoring indicates that the network has been stable since. Please contact help@eecs.berkeley.edu if you notice any ongoing issues.

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.
EECS Network Maintenance, 10/31 1-5PM
On Thursday, October 31 between 1 and 5PM, we will be performing network link migrations in preparation for retiring an old router. This maintenance will affect one of the EECS network’s paths to Campus and the Internet, however we expect no interruption as we have another redundant path which is able to handle our full traffic volume.
Update 10/31 16:22: This work has been completed without any significant interruption to network traffic. Please contact us at help@eecs.berkeley.edu if you notice any issues.
Soda and SDH Network Maintenance, Mon. 8/5 8PM
Tonight at 8PM, we will be performing maintenance on the network path between Soda Hall and Sutardja Dai Hall. Some Private Networks in Sutardja Dai will experience a brief interruption, but we do not expect this maintenance to affect any production networks (i.e. the general use wired and wireless networks). We will update this post when the work is complete, or if there is an unforeseen impact to the production networks.
Update 8:17PM: This work has been completed without any major network disruptions. Please contact us at help@eecs.berkeley.edu if you notice any ongoing issues.
Soda and Cory Network Maintenance, Thurs. 8/1 8PM
Tonight at 8PM, we will be performing maintenance on the network path between Soda Hall and Cory Hall. Some Private Networks in Cory Hall will experience a brief interruption, but we do not expect this maintenance to affect any production networks (i.e. the general use wired and wireless networks). We will update this post when the work is complete, or if there is an unforeseen impact to the production networks.
Update 8:52PM: This work has been completed without major impact and all networks are online. Please contact help@eecs.berkeley.edu if you notice any issues.
