EECS Department Websites down

August 2, 2013 by IRIS Staff

Starting around 11:20PM tonight, both of the EECS department websites, http://www.cs.berkeley.edu/ and http://www.eecs.berkeley.edu/, became unreachable. Staff are looking into the problem, but no known cause is apparent at this time.

UPDATE

[2013-08-03 00:06:57 | Jon Kuroda]

At around 11:57PM, both the EECS Department websites came back with minimal staff intervention. Additionally, the web interface for the EECS mail list server, https://lists.eecs.berkeley.edu/, returned after suffering a similar fate. A small number of internally facing systems were also affected.

At this time, there is no apparent cause.


UPDATE

[2013-08-06 23:41:59 | Robert McNicholas]

The department websites www.eecs and www.cs and the department mailing list server lists.eecs are all hosted on a small cluster of two servers. One of those servers was experiencing problems Friday evening that was interfering with a department service. In the course of trying to resolve that problem, www.eecs was rebooted twice and was unavailable from 23:19-23:22 and again from 23:30-23:52. lists.eecs was similarly not accpeting connections from 23:37-23:56.

The underlying problem is that these systems are very old. A disk error on one node seems to have initiated the failure. We hope to have these systems migrated to a new virtual machine environment in the next few months.
