We have been experiencing campus-level network instability since sometime around midnight, which is affecting the EECS and BWRC networks. Network team is investigating and working with the vendor to restore full network connectivity.
Update 2/11 6:41AM: The campus network team resolved these issues late Friday evening and our monitoring indicates that the network has been stable since. Please contact help@eecs.berkeley.edu if you notice any ongoing issues.
Microsoft will release their patches for the month on Tuesday, January 14th, 2025. Various IRIS Windows and Linux servers will be patched and rebooted Tuesday or Wednesday.
PRINT, WINTERM and WDS will automatically patch and reboot Wednesday, January 15th, at 3:00am. WINTERM may be unavailable until 10:00am Wednesday, depending on additional software updates.
Linux servers lists.eecs, iris2.eecs (for access to the network and roster databases), and login.eecs/login-mfa.eecs will be patched and rebooted Wednesday night. DNS servers cronus, themis, and rhea may also be briefly unavailable while rebooting at approximately 8:00pm Tuesday.
On Wednesday, January 15th, the departmental DHCP server is scheduled for downtime from 10pm to 10:30pm (actual downtime is expected to be shorter than scheduled).

[Read more…] about North campus power outage Jan 4, 2025Since some time last night, our mailing list server lists.eecs has been offline due to an issue with the system. Staff are beginning to investigate and an update will be posted here when available.
While the list server is offline, some emails will be delayed, and any messages sent through an EECS mailing list will not be delivered on time.
Please contact help@eecs.berkeley.edu if you have any questions.
After installing the most recent patches, this machine would not boot up. We reverted to a previous kernel and the system is now up.
Microsoft will release their patches for the month on Tuesday, December 10th, 2024. Various IRIS Windows and Linux servers will be patched and rebooted Tuesday or Wednesday.

[Read more…] about December IRIS Server PatchingTuesday 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.
[Read more…] about DNS disruption for eecs.berkeley.edu, Nov 19We 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.
[Read more…] about NetApp Fileserver Maintenance, Saturday November 30, 2024On Thursday, November 14th, between 6:30 and 9:45 AM, Cory Hall third floor wired and wireless networks will be offline due to electrical work being performed at the main service panel. Facilities is performing this work in order to restore electrical power to the Cory Hall Helpdesk.
Facilities is reporting that the west side of the third floor (which includes the network closet) will be without power from 6:30 – 9:30 AM. The network devices, particularly the wi-fi APs, will need some time to boot up after power is restored. We typically expect network connectivity to be restored within 10-20 minutes after power returns to the network closet.
Update 11/14 9:36AM: This work was apparently completed without any interruption to the network. Please contact help@eecs.berkeley.edu if you have any questions.

[Read more…] about November IRIS Server PatchingOn Thursday, October 31 between 1 and 5PM, we will be performing network link migrations in preparation for retiring an old router. This maintenance will affect one of the EECS network’s paths to Campus and the Internet, however we expect no interruption as we have another redundant path which is able to handle our full traffic volume.
Update 10/31 16:22: This work has been completed without any significant interruption to network traffic. Please contact us at help@eecs.berkeley.edu if you notice any issues.
