Soda Hall Network Maintenance, 12/27 12-1PM

by

Between 12 and 1PM on Tuesday, December 27th, we will be performing maintenance on the Soda Hall root switch. All Soda Hall wired and wireless networks will experience interruptions during this time, except for most of 290 Soda, which will remain online. (Some Instructional systems in 290 will be affected)

Update 12/27 2PM: This maintenance was completed and all networks should be back online. Please contact us at help@eecs.berkeley.edu if you have questions or notice any issues.

EECS Network Border Maintenance, 12/27 1-2PM

by

Between 1 and 2PM on Tuesday, December 27th, we will be performing a firmware upgrade on one of our two redundant border routers which connect the EECS networks to Campus and the Internet. No interruption is expected, as the other border router which is not being upgraded will be able to handle all network traffic during this maintenance.

Update 2:15P: This upgrade has been completed and both border routers are back online. Please email us at help@eecs.berkeley.edu if you notice any network issues.

EECS Network Border Maintenance, December 13-14

by

This week, we will be performing network maintenance to complete the decommissioning of our old border firewalls. The work will be performed in two stages; the first between 11AM-12PM on Tuesday the 13th, and the second between 11AM-12PM on Wednesday the 14th.

We do not expect this work to have any impact to network connectivity, as the vast majority of traffic flows were migrated to our new firewall earlier in the year.

Please email help@eecs.berkeley.edu if you have any questions, or if you notice any unusual network behavior.

Update 12/14: This work has been completed without any network impact. Please email us at help@eecs.berkeley.edu if you notice any issues.

IT Support During Winter 2022 Energy Curtailment

by

Due to the Winter Holiday, Energy Curtailment, and New Year’s Holidays, the Berkeley campus is officially closed for the period Friday, December 23 to Monday, January 2, reopening on Tuesday, January 3, 2023. 

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 Wednesday, December 21 through Wednesday, January 4, re-opening on January 5. If you need assistance between December 21-22 or January 3-4, please email help@eecs, and we may be able to schedule an appointment with you. 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 January 3.

Requests for network support or new IRIS accounts that are received after 5pm December 21 may not be processed until January 3, 2023.

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 January 3.

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

EECS-Secure Wi-Fi Shutting Down, January 4th

by

At 7AM on Wed. January 4th, the EECS-Secure wireless network will be permanently retired. We recommend all wireless devices switch to using eduroam to prevent any interruptions when EECS-Secure is shut down.

If you are having trouble using eduroam, or cannot do something on eduroam that does work on EECS-Secure, please email us at help@eecs.berkeley.edu, or visit our Helpdesk in person at 395 Cory Hall.

For additional information about EECS-Secure retirement and the overall wi-fi roadmap, please see our previous announcement from April.
