Tuesday afternoon and evening, November 19, we had a disruption of DNS resolution for the eecs.berkeley.edu domain on the campus nameservers. This meant that many systems outside of the EECS network were temporarily unable to resolve *.eecs.berkeley.edu hostnames — so people may have been temporarily unable to reach EECS websites or deliver email to some @eecs.berkeley.edu addresses.

We are scheduling a NetApp ONTAP upgrade, to apply a necessary update to our NetApp fileserver, from 8am to 12pm on Saturday, November 30, 2024.
All Home directories and Project shares (CIFS/SMB and NFS) may experience disconnection during the update that may cause data loss on active, open files. Please close your open files and save them before Saturday morning. Services (e.g. webservice) that depend on this storage will also be temporarily down or unresponsive.
When maintenance is completed, NFS clients should automatically resume normal operation, but a reboot should help if they don’t. CIFS clients (such as Windows and MacOS) may need to remount filesystems, or simply be rebooted.

System administrators in EECS may be familiar with our DNS nameservers cronus and rhea. We now have a new nameserver, physically located in Cory Hall, named themis. If your systems are typical DHCP clients, or you don’t use the EECS wired network, then you should have nothing to change.
We are planning to replace and retire rhea according to the following schedule:
- Thu Oct 15 — We will update our DHCP configuration, telling Cory Hall DHCP clients to use themis and cronus, and telling other DHCP clients to use cronus and themis.
- November/December — We will monitor any continued usage of rhea for DNS, and periodically alert system administrators so they can update their systems to use themis instead.
- early January — We will retire rhea, but will point its name and IP address at cronus.
2024 Synopsys renewal in progress
If you use Synopsys software on EECS Instructional or research systems, you may be seeing an alert that the current licensing expires on September 25. Staff are already in progress of renewing Synopsys licensing, and our vendor representative is working to get us new license files as soon as possible.
