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 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.

We will be performing an OS upgrade on our departmental NetApp filers (upgrading from OnTAP version 9.7 to 9.8), which will require a service outage from 3pm to 9pm on Monday, January 3, 2022. All NFS and CIFS access to the filer (home and project storage) will be down during that time. Services (e.g. webservice) that depend on this storage will also be down or unresponsive.
While we are scheduling a 6 hour maintenance window, we will attempt to minimize the service outage if possible.
When maintenance is completed, NFS clients should automatically resume normal operation. CIFS clients (such as Windows and MacOS) may need to remount filesystems, or simply be rebooted.

At 6AM on Monday, December 20, we will be migrating these two Soda Hall networks to our new border firewall:
128.32.112.0/24 (Soda Hall 3rd floor: primarily rooms 330, 340, and many offices along the East wall)
128.32.132.0/24 (Soda Hall 4th floor: primarily RISE Lab)
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.
