Wired Networking

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.

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.

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.

At 5AM on Tuesday, May 17th, we will be performing firmware upgrades on various Soda Hall network hardware. Wired networks in Soda and Jacobs Halls will be unavailable for approximately 15 minutes beginning at 5:00AM; BWRC networks will also be isolated from EECS, campus, and the Internet during this short period. Wireless networks in Soda Hall will experience a number of interruptions throughout the two hour period. We expect all connectivity will be restored by 7AM.

We do not expect significant interruption to most IRIS services hosted in 290 Soda.

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.

Between 5 and 7AM on Monday, May 16th, we will be performing firmware upgrades on various Cory Hall network hardware. Wired networks will be unavailable for approximately 15 minutes beginning at 5:00AM. Wireless networks 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 6:30AM. Please contact us at help@eecs.berkeley.edu if you have any questions, or notice any lingering issues.

Tomorrow morning, 2/25 at 6AM, we will be rebooting the Soda Hall core router in order to apply a configuration change which will resolve an issue currently affecting a small portion of network traffic. As a result, we expect most EECS network paths will be unavailable for up to 15 minutes beginning at 6AM. Some systems or services (e.g. nfs) may have connectivity issues and may need to be restarted or rebooted after this maintenance.
