Updated winterm.eecs now available

by

An updated winterm.eecs, running Windows Server 2025, is now available as a Windows Remote Desktop Server. As soon as the new DNS records propagate, your connection to winterm.eecs will find this updated OS with updated software versions.

Access and software is much like the previous winterm.eecs, though with a desktop experience that’s similar to Windows 11. See our EECS Login Servers page for more information on using winterm.eecs.

If you need to access the previous winterm.eecs (e.g. to copy files kept locally), it will remain online for the next week or two as winterm-old.eecs.berkeley.edu. Feel free to contact help@eecs if you need us to copy your profile from winterm-old to the new winterm.

Soda 2F Network Interruption, 9/18 10:41 AM

by

Networks on the second floor of Soda Hall were unavailable for approximately 5-10 minutes today beginning at 10:41 AM. This occurred due to a switch crash during troubleshooting a memory leak.

The network is now stable, but the memory leak issue still exists and requires further network disruption to resolve. We will be attempting to address this during tonight’s already-scheduled Soda Hall electrical shutdown.

Please contact us at help@eecs.berkeley.edu if you have any questions.

Soda Hall Electrical Shutdown and BWRC Network Outage, 9/18 7PM

by

Following up on the previous scheduled power outage, the electricians still need to try addressing the failed circuit breaker on the first floor of Soda, since first floor lights and Soda Hall main supply and exhaust fans remain off, and parts of the building are becoming unbearably hot due to lack of airflow.

Similarly to last time, Soda Hall will be completely without power beginning at 7PM. Please shut down your systems before 7PM on Thursday to avoid any issues. This includes all systems in the Soda 340 server room. Power is expected to be restored by 8:15PM.

We expect all IRIS services to remain available, due to a combination of battery backups and redundant servers in other buildings.

BWRC networks will be offline during this shutdown, as they are dependent on Soda Hall.

Please contact us at help@eecs.berkeley.edu if you have any questions.

Temporary loss of DHCP network support for some desktops, Sep 13

by

Late Saturday, September 13, an issue arose with our automatic DHCP support of registered desktop machines (wired network support of desktops/workstations without fixed IP addresses).

This appears to have affected devices with hostnames beginning with letters r through z, which have network registrations older than one year. Those devices would have lost their DHCP lease, and so would have lost their network connection, sometime early Sunday.

We have restored a known-good version of the DHCP support file for these hosts, and they should generally come back online with no intervention needed. Some devices may need to be rebooted, if they don’t come back online automatically.

Staff are continuing to investigate the root cause of the issue.

Soda Hall Electrical Shutdown and BWRC Network Outage, 9/8 7PM

by

We have been informed by facilities of the need for a shutdown of all Soda Hall electrical systems on Monday, September 8th, at 7PM. We do not have a clear idea of the duration, but 1-2 hours appears to be a reasonable estimate.

Soda Hall will be completely without power beginning at 7PM. Please shut down your systems before 7PM on Monday to avoid any issues. This includes all systems in the Soda 340 server room.

We expect all IRIS services to remain available, due to a combination of battery backups and redundant servers in other buildings.

BWRC networks will be offline during this shutdown, as they are dependent on Soda Hall.

Please contact us at help@eecs.berkeley.edu if you have any questions.

Update: This work has been rescheduled, and the text above has been updated with the current schedule.

Network Instability, 8/31 9PM – 9/1 2AM

by

Portions of the EECS and campus networks experienced instability last night between 9PM and 2AM due to DDoS-like traffic directed at a system on the EECS network. This ended without intervention from network staff; we are investigating and remaining on standby in case this reoccurs.

Please contact us at help@eecs.berkeley.edu if you have any questions or notice any issues.

Jacobs Hall Network Maintenance, Tue. 8/12 10PM – Wed. 8/13 7:30AM

by

We will be performing Jacobs Hall network maintenance overnight from Tuesday, August 12th at 10PM to Wednesday, August 13th at 7:30AM. This maintenance is to replace the existing end-of-life router and switches with newer campus standard devices.

All wired and wireless networks in Jacobs Hall will be unavailable between 10PM Tuesday night and 7:30AM Wednesday morning. We expect all networks to be back online by 7:30AM.

Update: This work has been completed. Please contact us at help@eecs.berkeley.edu if you notice any network issues.
