Between 11AM and 4PM on Saturday, May 13th, we will be replacing the access switches which provide wired and wireless network connectivity to the 3rd floor of Soda Hall.
All wired and wireless networks on the third floor, except wired networks in server room 340, will be interrupted during this time.

Wired networks on the Cory Hall second floor were unavailable until approximately 10:51AM this morning due to unintended behavior by the 2nd floor access switch. Connectivity has been restored and network staff will be performing non-disruptive testing this afternoon to determine the exact root cause.
Please email us at help@eecs.berkeley.edu if you continue to notice any network related issues.
Between 11AM and 4PM on Saturday, April 29th, we will be replacing the access switches which provide wired and wireless network connectivity to the basement, first, second, and third floors of Cory Hall.

We are currently investigating a partial wired network outage on the third floor of Cory Hall. Wireless networks should not be affected. Updates will be posted here when available.
Update: We identified an issue with one of the third floor switches and network connectivity has been restored. Please email us at help@eecs.berkeley.edu if you notice any continuing network issues.
IRIS network staff are investigating some network interruptions that began just before 6:30pm.
Update: the cause was identified and all networks were stabilized around 8pm.
Between 12 and 4PM on Thursday, December 29th, we will be replacing the access switches which serve the second floor of Cory Hall. During this time, there will be significant disruptions to the wired and wireless networks on the second floor, the second floor mezzanine, and possibly also the Cory Hall roof.
Update 12/29 16:30: This maintenance is complete. Please email help@eecs.berkeley.edu if you notice any network issues.
Between 11AM and 4PM on Wednesday, December 28th, we will be performing maintenance on the Soda Hall core router. Most Soda Hall wired networks will not be affected by this maintenance due to redundant links. However, Soda Hall and BWRC wi-fi, as well as BWRC’s uplink to the outside world, will experience a number of interruptions during this time.
Update 12/28 15:15: This work has been completed and all networks are online. Please email help@eecs.berkeley.edu if you notice any issues.
Between 12 and 1PM on Tuesday, December 27th, we will be performing maintenance on the Soda Hall root switch. All Soda Hall wired and wireless networks will experience interruptions during this time, except for most of 290 Soda, which will remain online. (Some Instructional systems in 290 will be affected)
Update 12/27 2PM: This maintenance was completed and all networks should be back online. Please contact us at help@eecs.berkeley.edu if you have questions or notice any issues.
Between 1 and 2PM on Tuesday, December 27th, we will be performing a firmware upgrade on one of our two redundant border routers which connect the EECS networks to Campus and the Internet. No interruption is expected, as the other border router which is not being upgraded will be able to handle all network traffic during this maintenance.
Update 2:15P: This upgrade has been completed and both border routers are back online. Please email us at help@eecs.berkeley.edu if you notice any network issues.
