Multiple Services Offline for About Eight Hours

December 28, 2008 by IRIS Staff

The EECS website, FTP server, Jabber server and Sympa mailing-list server were offline for about eight hours on Sunday, Dec 28, 2008 beginning at 2:48 p.m.

The virtualization cluster that hosts these services experienced a failure when the network switch that supplies its management network was rebooted during the [scheduled network maintenance](https://iris.eecs.berkeley.edu/news/2246-eecs-network-maintenance-sunday-dec). We didn’t notice the failure until this evening, but were able to restore service quickly once we realized what was wrong.

I apologize for the length of the downtime and am planning on working to make the cluster more robust and improve our notification and monitoring so that any future issues will be noticed more quickly.
