Wired network service
At 6AM on Monday, Feb. 7, we will be disabling our old/legacy uplinks to the campus network. Our new uplinks were finalized last year and traffic has been using both pairs of links since then. As a result, we expect no impact from this maintenance.
Please contact help@eecs.berkeley.edu if you have any questions or concerns.
[Read more…] about Network Border Maintenance, 2/7 6AMUpdate 2/2: We are postponing this work due to some conflicts that have arisen. There will be a new post for the new maintenance window, but we are currently targeting 2/14.
At 6AM on Monday, February 7th, we will be migrating a number of networks to our new border firewall. This will affect many wired networks in Soda and Cory Halls, as well as EECS wireless in all locations except BWRC.
There will be a brief interruption to each of these networks as they are migrated. In addition, the ipv6 subnets used by EECS-Secure and EECS-PSK clients will change. You can read the full post below for details.
[Read more…] about Cancelled: Soda, Cory, and Wi-Fi Firewall Migrations, 2/7 6AMAt 6AM on Monday, January 31, we will be migrating these networks to our new border firewall:
128.32.48.0/24 (Cory Hall 1st floor wired)
128.32.134.0/24 (Cory Hall 1st floor Mezzanine wired)
169.229.34.0/24 (Cory Hall 2nd floor wired)
128.32.171.0/24 (Cory Hall areas 545 and 550A)
There will be a brief interruption to these networks as they are migrated. After the migration, we encourage system administrators to test that traffic across the firewall is behaving as expected.
Please contact us at help@eecs.berkeley.edu with any questions or concerns.
[Read more…] about Cory Hall Firewall Migrations, 1/31 6AMAt 6AM on Monday, January 24, we will be migrating these two Soda Hall networks to our new border firewall:

[Read more…] about Soda Hall Firewall Changes, Mon. 1/24 6AMMost network paths were unavailable today between approx. 13:10 – 13:20 due to a router crash apparently caused by a routine procedure. We are investigating why this occurred. Please contact us at help@eecs.berkeley.edu if you notice any continuing issues.
Sutardja Dai Hall networks experienced a number of interruptions and outages this morning between 6:44 and 11:21, as a result of electrical maintenance in the building which we were not informed of in advance.
We believe the network to be fully recovered at this time. Please contact us at help@eecs.berkeley.edu if you notice any ongoing issues.
During curtailment, on Mon-Wed December 27th-29th, we will be migrating the Cory Hall access switches from the old core switch to the building core router.
We expect wired networks will be interrupted for about a minute during the migration. Wireless networks may be interrupted for longer (possibly up to 15 minutes). This post will be updated as each stage is completed, or if any schedule changes become necessary.
Monday 12/27 11:30AM-2PM:
1F Cory (except room 165) completed!
Tuesday 12/28 12-3PM:
165 Cory completed!
3F Cory completed!
Wednesday 12/29 12-3PM:
4F Cory completed!
5F Cory completed!
Please contact us at help@eecs.berkeley.edu with any questions or concerns.

128.32.132.0/24 (Soda Hall 4th floor: primarily RISE Lab)
