Wireless Network Maintenance, Fri. 9PM – Sat 7AM

by

Between 9PM Friday 9/2 and 7AM Sat 9/3, the wireless networks for all EECS buildings (except Calvin) will be migrated to a new set of campus wireless controllers, with the aim of reducing overall load on the campus wireless networks. During this time, there will be some interruptions to wireless networks in Soda, Cory, Sutardja Dai, Jacobs, Blum, HMMB, and BWRC.

Additional work on the wireless networks is planned throughout the weekend, but that work is not expected to be disruptive.

For more details and up to date status information, please visit https://systemstatus.berkeley.edu/.

Please visit our helpdesk in 395 Cory Hall next week during business hours if you experience any new issues with the wi-fi networks after this maintenance.

Soda and Cory Halls Network Maintenance, Thu. 7/14 6AM

by

At 6AM on Thursday, July 14th, we will be performing emergency maintenance in order to address recent network instability. Soda and Cory Hall wired and wireless networks will experience interruptions during this time, and we expect all connectivity will be restored by 7AM. IDSG services in 290 Soda (such as file service) will not be interrupted, but Instructional services in 290 will be interrupted.

BWRC will also be isolated from Campus and the Internet for a period during this maintenance.

Some systems or services such as nfs mounts may need to be restarted after this maintenance. Please contact us at help@eecs.berkeley.edu if you have any questions.

Update 7/14: This maintenance has been completed. Wired networks have been restored, and wireless networks are coming back online.

Sutardja Dai Hall Network Maintenance, Wed. 7/13 6AM

by

At 6AM on Wednesday, July 13th, we will be performing emergency maintenance in order to address recent network instability. Sutardja Dai wired and wireless networks will experience interruptions during this time, and we expect all connectivity will be restored by 7AM.

Some systems or services such as nfs mounts may need to be restarted after this maintenance. Please contact us at help@eecs.berkeley.edu if you have any questions.

Update 7/13 6:28AM: This maintenance has been completed and most connectivity has been restored. Wi-fi networks in some areas are still coming back online, but we anticipate all connectivity will be restored by start of business.

Firewall Migrations for Private Networks, 6/27 6AM

by

At 6AM on Monday, June 27, we will be migrating various Private Networks to our new border firewall. After this maintenance, our migrations to the new firewall will be complete.

This will affect all networks using addresses between 169.229.3.0 and 169.229.3.83. There will be a brief interruption to each Private Network as they are migrated.

We encourage network administrators to test their systems on Monday morning after this maintenance is complete, to ensure their traffic is being properly handled by the new firewall.

Update 6/27 6:05AM: This maintenance is complete. Please contact us at help@eecs.berkeley.edu if you have questions or notice any issues.

BWRC Firewall Migration, 6/9 6AM

by

At 6AM on Thursday, June 9th, we will be migrating BWRC networks to the new border firewall. BWRC’s connectivity to EECS, Campus, and the Internet will be briefly disrupted at this time. This will affect all wired and EECS wireless networks at BWRC.

We encourage system administrators to test their systems on Thursday morning after this maintenance is complete, to ensure their applications and services are being properly handled by the new firewall.

Please contact the BWRC Sysadmins or help@eecs.berkeley.edu if you have any questions.

Update 6/6: Due to a conflict with other work being performed at BWRC, this maintenance has been moved from Tuesday 6/7 to Thursday 6/9. The original post has been edited accordingly.

Update 6/9: This maintenance has been completed. Please contact BWRC Sysadmins or help@eecs.berkeley.edu if you notice issues with the new firewall.

EECS Network Outage, 5/16 9:32AM

by

There was an unplanned outage to the EECS network this morning from 9:32 until approximately 9:46 this morning due to a router crash. The outage primarily affected Soda and Jacobs Halls as well as BWRC; but there was also some lesser effect in other locations. This was unrelated to the planned maintenance which occurred earlier this morning.

Network service has been restored, and we are investigating the cause of the crash. Please email help@eecs.berkeley.edu if you notice any ongoing issues.

Sutardja Dai and Blum Halls Network Maintenance, Thu. 5/19 5-7AM

by

Between 5 and 7AM on Thursday, May 19th, we will be performing firmware upgrades on various Sutardja Dai and Blum Hall network hardware. Wired networks in SDH will be unavailable for approximately 15 minutes beginning at 5:00AM. Wireless networks in both buildings will experience a number of interruptions throughout the two hour period. We expect all connectivity will be restored by 7AM.

We recommend system administrators check their systems on Monday morning after 7AM to verify they are working as expected. Some systems or services, such as nfs mounts, may need to be restarted.

This maintenance is complete as of 6:20AM. Please contact us at help@eecs.berkeley.edu if you have any questions or notice any lingering issues.

Soda, Jacobs, and BWRC Network Maintenance, Tue. 5/17 5-7AM
