Soda 3F Wi-Fi Outage, 4/4/22

April 4, 2022 by Derek Calderon

Wi-Fi networks for a large portion of Soda Hall third floor are offline since 7:20 this morning due to a switch failure. Staff are currently in transit to install a replacement.

Update 11:27: Wi-fi service in most areas was restored around 10:35. The remainder was restored at 11:25. Please contact help@eecs.berkeley.edu if you notice any ongoing issues.

EECS Network Maintenance, 2/25 6AM

February 24, 2022 by Derek Calderon

Tomorrow morning, 2/25 at 6AM, we will be rebooting the Soda Hall core router in order to apply a configuration change which will resolve an issue currently affecting a small portion of network traffic. As a result, we expect most EECS network paths will be unavailable for up to 15 minutes beginning at 6AM. Some systems or services (e.g. nfs) may have connectivity issues and may need to be restarted or rebooted after this maintenance.

February 22, 2022 by Derek Calderon

Cory Hall 2nd Floor networks went offline this afternoon, 2/22, at 12:51PM due to a malfunctioning switch. The switch was restored remotely and wired networking returned at 1:13PM. Wireless networking has not yet fully recovered and we are working on this.

Firewall Migrations for Many Networks, 2/22 6AM

February 15, 2022 by Derek Calderon

At 6AM on Tuesday, February 22 at 6AM, we will be migrating a large number of networks to our new border firewall. This will affect the majority of wired networks in Soda, Cory, and Sutardja Dai Halls. EECS-Secure and EECS-PSK in all locations except BWRC will also be affected.

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.

We encourage system administrators to test their systems on Tuesday morning after this maintenance is complete, to ensure their applications are being properly handled by the new firewall.

BWRC Network Outage, 2/7

February 7, 2022 by Derek Calderon

BWRC networks are offline since around 13:10 today due to an apparently external cause. Staff are going onsite to investigate.

Update: The issue self-resolved around 13:48, but we believe this to have been an outage of the AT&T circuit which currently serves BWRC. We have plans to move this link to a more stable service later this week.

Cancelled: Soda, Cory, and Wi-Fi Firewall Migrations, 2/7 6AM

January 31, 2022 by Derek Calderon

Update 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.

January 18, 2022 by Derek Calderon

Most 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 Network Disruption, 1/6/22

January 6, 2022 by Derek Calderon

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.

Cory Hall Network Maintenance, 12/27-29

December 20, 2021 by Derek Calderon

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.
