EECS-Secure Authentication Unavailable 10/11/17

by

The authentication service for EECS-Secure was unavailable from 00:17 to 13:35 today. This was caused by a bad update that was automatically pushed to our servers by the vendor. We did not notice the issue or receive any trouble reports, so it went undetected until an alert was received from the vendor at 13:25.

The alert included a fix which we applied and service was restored by 13:35. During the outage, machines were unable to connect to EECS-Secure.

Information from the vendor about the bad update was posted at the following URL: http://community.arubanetworks.com/t5/Security/ClearPass-Policy-Server-is-down-after-the-recent-AV-AS-update/td-p/309698

Please contact help@eecs.berkeley.edu if you are still experiencing network problems.

Soda 5F South Network Issue

by

We are currently experiencing brief, intermittent losses of connectivity to Soda’s 5B network closet which serves the south side of the fifth floor.

The outages last approximately one minute and are spaced several hours apart. They appeared to be due to a fault in the 5B switch’s primary uplink to the BDF, so the primary link has been temporarily disabled in favor of the backup link.

As the issue is not currently severe we plan to investigate further on Monday. If things escalate, we will intervene sooner.
