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.

Temporary LDAP authentication failure

by

We experienced a failure of EECS LDAP authentication, from about 5:50pm to 10:30pm, due to routine patches changing some file permissions for saslauthd. The issue has been corrected, and LDAP authentication is working again.

The problem may have been most noticeable when attempting to login to various EECS web forms (e.g. system registration or user account request forms).

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.
