Cory 3F Networks Offline, Morning of Tue. 5/21

by

Due to planned electrical work, all Cory Hall third floor wired and wireless networks will be offline during the early morning on Tuesday, May 21st. We expect the network to be unavailable beginning at 5AM, and all connectivity should be restored by 10AM at the latest.

Update 5/21 10:08: The electrical work took slightly longer than expected, but all networks should now be back online. Please email us at help@eecs.berkeley.edu if you notice any issues.

lists.eecs.berkeley.edu mail delivery issues

by

We have had reports of some undelivered mail sent via mailing lists on lists.eecs.berkeley.edu. Upon investigating, Google / bMail is refusing to accept some email sent from lists.eecs.berkeley.edu, beginning early on April 24th . We believe this is due to some changes made at the campus level intended to improve mail reliability and reduce spam. We are working with the people running this project to try to determine the cause of the problem and arrive at a resolution.

If you believe you have been impacted by this, any reports of definitely missed emails would be helpful to us in assessing the scope of this problem.

In the meantime, we suggest that any important or time critical emails be also sent directly to individuals instead of relying entirely on mailing lists. For important emails that have been sent already, you may wish to follow up with a phone call or email sent directly to their bMail account.

This article will be updated as we learn more.

Update April 29, 4pm: This problems seems to have resolved itself. There was no definitive diagnosis unfortunately. We will continue to monitor delivery rates on select mailing lists.

LDAP server upgrade, Monday Apr 29, 6pm

by

The IRIS LDAP servers (ldap.eecs.berkeley.edu) provide usernames and passwords for many EECS applications and servers. On Monday, April 29th at 6pm, we will be upgrading these servers and their related load balancers to Red Hat 8. We plan to gracefully fail the old servers over to the new with no loss of service. As part of this upgrade, new SSL certificates have also been installed. Those accessing our servers programmatically might notice the certificate upgrade, but most users should not see any changes.

Update April 29 6:20pm: The server switchover has been completed. The only issue so far was with a server that was trying to use an older security protocol, TLS 1.1. The new servers require a minimum of TLS 1.2. Please check this setting if you are having problems.
