Wired Networking

Between 11AM and 5PM on Tuesday, December 26th, we will be performing maintenance on one of the EECS core routers in Soda Hall in preparation for various other projects occurring in 2024. We expect that this maintenance should not affect any network traffic; however there is the possibility of a brief (~5 minute) outage to some networks in the event of an unforeseen circumstance.

Update 12/26 14:46: This maintenance has been completed without any impact to network service. Please contact us at help@eecs.berkeley.edu if you are experiencing any network issues.

Between 12PM and 4PM on Wednesday, December 27th, we will be replacing the access switches which provide wired and wireless network connectivity on the 4th through 7th floors of Soda Hall.

During this time, wired and wireless networks on the 4th through 7th floors will experience various interruptions. Note that the Sky Computing Lab will not be affected, as the switch serving that area was already upgraded during a previous maintenance.

Update 12/27 13:24: This work has been completed and all networks are back online. Please contact us at help@eecs.berkeley.edu if you notice any connectivity issues.

Tonight (night of Dec.14 / morning of Dec.15) at 2AM we will be performing a software upgrade on one of the switches providing wired and wireless connectivity on the third floor of Soda Hall.

There will be a brief (approximately 5 minute) interruption to networks in the following areas:
– Wired networks in rooms 310-329, 331-333, 364A, and 373-398
– Wireless networks in rooms 373-395 and immediately surrounding areas

The following areas will not be affected:
– Wired networks in rooms 300-306A, 330, 340-349, 367-369
– Wireless networks in rooms 302-349 and immediately surrounding areas

Update: This work was completed on schedule and without any unexpected impact, but we neglected to update this post in a timely manner.

EECS Networks were unstable from 1AM to 7:44AM due to an apparent issue on the 4th floor of Soda Hall. The 4th floor has been isolated in order to stabilize the wider network, and we are now assessing the situation in that area.

Between 11AM and 4PM on Saturday, August 12th, we will be performing maintenance on network switches serving the south side of Soda 4th floor. Wired and wireless networks in the Sky Computing Lab, classroom 405, conference room 411, and the 4th floor main hallway will experience a number of disruptions during this maintenance window.

Update 8/12 14:39: This maintenance is complete and all networks should be online. Please contact us at help@eecs.berkeley.edu (or @dcalderon on Sky Slack) if you notice any ongoing issues.
