Investigating Windows mount issue with new fileserver

by

We have reports of problems with CIFS mounts of home directories and project shares from the new NetApp fileserver. CIFS is typically used by Windows or mobile clients. Staff are investigating and will report here as we learn more.

NFS mounts (typically unix/linux) are working as expected.

Cory Hall partial power outage, Thursday, April 16, 2026 — postponed

by

Campus Facilities Services is scheduled to perform an urgent repair, replacing the main circuit breaker serving Cory Hall’s 188 Lab and 1st floor Mezzanine. An email from Logan Baldini, our Director of Facilities and Capital Projects, already went out on April 8 to Cory Hall occupants.

Work will take place Thursday, April 16, 8:15pm — 11:15pm. Power will be shut down for most of the south and west side of Cory Hall, including stairwells. Detailed room breakdown is available via Google Doc, attached to the email sent out by Logan.

We do not expect to lose power to our network switches and routers in Cory Hall during this work. If we do have unexpected power loss to our network equipment, then access to services hosted in Cory Hall (e.g. any research or instructional servers in 165 Cory) will be affected; we will monitor our equipment, but would expect service to resume once the electrical work is completed.

UPDATE

[2026-04-14 | larsrohr ]

This work has been postponed by Campus Facilities Services. We will update or re-post when we have an revised schedule to report.

EECS Border Firewall Changes, Mon. March 23

by

On Monday, March 23rd, we will be adding some new ports to the list of ports that are blocked by the EECS border firewall.

For detailed information about the changes, please see our EECS Firewall Ports page (this page requires login). The list of ports that we will add to the block list is at the bottom of that page.

Update 3/23 8:05AM: These changes have taken effect, and the new ports are now being blocked from off-campus. Please contact us at help@eecs.berkeley.edu if you have any questions or notice any issues.

Wireless Networks Offline, Monday 1/5

by

As of about 11:51 AM: wireless networks are offline due to a power issue in one of the campus network core sites. Wired networks are unaffected and continue to operate normally. We will update again when we have more information about the status of the campus network core.

Update 13:36: Campus has begun restoring power to the network core using temporary connections, so we expect to see some wi-fi service resume. However, wi-fi may experience some continuing instability as the work to restore full power goes on.

Update 17:02: Power has been restored and network services should be fully available. There may be some late-night wi-fi disruptions as staff perform some cleanup work.

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

IT Support During Winter 2025 Energy Curtailment

by

Due to the Winter Holiday, Energy Curtailment, and New Year’s Holidays, the Berkeley campus is officially closed for the period Wednesday, December 24 to Thursday, January 1, reopening on Friday, January 2, 2026. Additionally, much of campus is on reduced support for December 22-23, January 2, and the week of January 5-9.

All departmental computing servers will remain on and should be available during the break, but there will be no staff on site to provide any computing support or handle any requests. Automatic monitoring systems will alert staff to critical infrastructure problems, and any such problems will be dealt with on a best-effort basis.

The IRIS Helpdesk office will be closed Monday, December 22 through Friday, January 2, re-opening fully on Monday, January 12. If you need assistance during the week of January 5-9, please email help@eecs, and we should be able to reply and schedule an appointment with you if needed. Problem reports can be left on the Helpdesk voice mail (510-642-7777) or emailed to help@eecs during the campus closure period, but staff may not receive or reply to these messages until at least January 5.

Requests for network support or new IRIS accounts that are received after noon Thursday, December 18 may not be processed until January 5, 2026.

During the break, Instructional labs will be locked, but the main servers will remain online (for details, see the Instructional website). Instructional support staff will occasionally monitor inst@eecs email over the break. Please be aware, though, that staff may not be able to respond or reply to messages until at least January 5.

Computing support staff will be monitoring their email when possible, so please use standard email addresses to report any urgent problems. As a reminder:

Instructional Computing Environment: inst@eecs

Research / Staff Computing Environment: help@eecs
