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.

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.

The IRIS Mailing List Server lists.eecs.berkeley.edu will be undergoing routine maintenance tonight, Dec 22, beginning at 6pm. The server should be back no later than 6:30pm. The web interface will be unavailable during this time, and any mail sent to a list on lists.eecs.berkeley.edu will be held and distributed after the server is back up.
[Read more…] about Mailing lists maintenance, Dec 22 6pmWe 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.
