Wired network service
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.
We have a power outage on part of campus, affecting at least Cory and Soda Halls, starting at just after 8am this morning. All EECS systems and networks may be unavailable until power is restored.

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.
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.
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.

At 10PM on Thursday, July 18th, we will be performing firmware upgrades on various BWRC network devices in order to address a bug in the current version.
All wired and wireless networks at BWRC will be offline for approximately 5-15 minutes during the upgrade.
Update 7/18 22:12: The upgrades have been completed and all networks are back online. Please contact us at help@eecs.berkeley.edu if you notice any ongoing issues.
At 10PM on Wednesday, July 17th, we will be performing firmware upgrades on various Soda Hall network devices in order to address a bug in the current version.
All wired and wireless networks in Soda Hall, except for those on the first and second floors and in machine room 340, will be offline for approximately 5-15 minutes during the upgrade.
Update 7/17 22:12: This work is complete and all networks are back online. Please contact us at help@eecs.berkeley.edu if you notice any ongoing issues.
Due to planned electrical work, all Cory Hall third floor wired and wireless networks will be offline during the morning on Tuesday, June 25th. Per facilities, power (and therefore network) will be unavailable between 7:30am and 12:30pm. The network, particularly wi-fi, may take as long as 15 minutes to fully come online after power is restored.
Please contact us at help@eecs.berkeley.edu if you have any questions.
[Read more…] about Cory 3F Networks Offline, Morning of Tue. 6/25Just before 6:30pm, the campus experienced a wide-spread power outage. Most of the east side of campus remains without power at the time of this writing. There is currently no estimate for when power will be restored.
IRIS services in Soda and Cory will be either shut down imminently, or will soon become unavailable, as UPS power is used up. Once power is safely restored to campus, we will work to bring services back online to the best of our abilities.
