Resolved Incidents

Jacobs Hall Network Outage, 5/8

by

We are investigating an outage of Jacobs Hall wired networks which began approximately 2:30AM on May 8th. We currently believe that wi-fi is unaffected. An update will be posted this afternoon when we have more information.

Update: All Jacobs Hall network service was restored shortly after 2PM. Please email help@eecs.berkeley.edu if you notice any continuing issues.

Update to Domain Controller Group Policy

by

We are implementing an update to Group Policy that affects our Windows Domain Controllers this morning at 10am. No impact is expected on end users, but we are mindful that a similar change last week caused an unexpected problem with LDAP-auth (see https://iris.eecs.berkeley.edu/news/resolved-incidents/eecs-ldap-logins-not-working/).

This update improves the security profile of our Domain Controllers. In particular, we are removing explicitly-listed Null Session Named Pipes, as is best practice.

Soda 3F Wi-Fi Outage, 4/4/22

by

Wi-Fi networks for a large portion of Soda Hall third floor are offline since 7:20 this morning due to a switch failure. Staff are currently in transit to install a replacement.

Update 11:27: Wi-fi service in most areas was restored around 10:35. The remainder was restored at 11:25. Please contact help@eecs.berkeley.edu if you notice any ongoing issues.

Firewall Migrations for IRIS NetApps and Instructional Servers, 3/21 6AM

by

At 6AM on Monday, March 21, we will be migrating the following networks to our new border firewall:

169.229.3.96/27 (Instructional Support Group servers)
169.229.3.128/26 (IRIS NetApp file servers, including home and project shares)

There will be a brief interruption to these networks as they are migrated. This will affect all home, project, and other file storage provided by the IRIS NetApps. After the migration, we encourage system administrators to test that connections to the NetApps are behaving as expected. Some file service clients may need to be rebooted or have their nfs service restarted.

Please contact us at help@eecs.berkeley.edu with any questions or concerns.

by

The Department mailing list server lists.eecs.berkeley.edu will be down for maintenance this Wednesday, March 16, 2022 beginning at 5pm. During this maintenance, the Sympa mailing list software will be upgraded to the latest version, which we hope will fix a few bugs. We expect the outage to last no longer than 2 hours. Any mail sent to a list during this time will be held for delivery after the upgrade is complete.
