Instructional & Research Information Systems
Wired network service
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.
This week, we will be performing network maintenance to complete the decommissioning of our old border firewalls. The work will be performed in two stages; the first between 11AM-12PM on Tuesday the 13th, and the second between 11AM-12PM on Wednesday the 14th.
We do not expect this work to have any impact to network connectivity, as the vast majority of traffic flows were migrated to our new firewall earlier in the year.
Please email help@eecs.berkeley.edu if you have any questions, or if you notice any unusual network behavior.
Update 12/14: This work has been completed without any network impact. Please email us at help@eecs.berkeley.edu if you notice any issues.
This afternoon at 1PM, we pushed a configuration change to the EECS border firewall which affects the firewall’s access to various configuration resources. This change was tested and we anticipate no effect; however please email help@eecs.berkeley.edu if you notice any of your machines or services suddenly become unreachable from outside the EECS network.
Beginning at 8:05 this morning, there is a partial wired network outage on the first floor of Cory Hall. The apparent cause is a failed switch; staff will arrive onsite this afternoon to investigate further and attempt repair.
We do not believe that wi-fi networks, or wired networks on other floors, are affected at this time.
Update 15:45: Network service was restored just prior to 3PM this afternoon. Please email help@eecs.berkeley.edu if you notice continuing network issues.
At 6AM on Thursday, July 14th, we will be performing emergency maintenance in order to address recent network instability. Soda and Cory Hall wired and wireless networks will experience interruptions during this time, and we expect all connectivity will be restored by 7AM. IDSG services in 290 Soda (such as file service) will not be interrupted, but Instructional services in 290 will be interrupted.
BWRC will also be isolated from Campus and the Internet for a period during this maintenance.
Some systems or services such as nfs mounts may need to be restarted after this maintenance. Please contact us at help@eecs.berkeley.edu if you have any questions.
Update 7/14: This maintenance has been completed. Wired networks have been restored, and wireless networks are coming back online.
At 6AM on Wednesday, July 13th, we will be performing emergency maintenance in order to address recent network instability. Sutardja Dai wired and wireless networks will experience interruptions during this time, and we expect all connectivity will be restored by 7AM.
Some systems or services such as nfs mounts may need to be restarted after this maintenance. Please contact us at help@eecs.berkeley.edu if you have any questions.
Update 7/13 6:28AM: This maintenance has been completed and most connectivity has been restored. Wi-fi networks in some areas are still coming back online, but we anticipate all connectivity will be restored by start of business.
At 6AM on Monday, June 27, we will be migrating various Private Networks to our new border firewall. After this maintenance, our migrations to the new firewall will be complete.
This will affect all networks using addresses between 169.229.3.0 and 169.229.3.83. There will be a brief interruption to each Private Network as they are migrated.
We encourage network administrators to test their systems on Monday morning after this maintenance is complete, to ensure their traffic is being properly handled by the new firewall.
Update 6/27 6:05AM: This maintenance is complete. Please contact us at help@eecs.berkeley.edu if you have questions or notice any issues.
