Mailing List Web Interface down

by

The web interface to the Department’s mailing list server lists.eecs.berkeley.edu is unavailable. There is a problem authenticating against our LDAP servers over SSL. This problem is currently being investigated, and we hope to have the web server available soon.

Mail delivery to lists hosted on lists.eecs is not affected. No mail has been delayed or lost.

If you need assistance managing your list during this outage, please send your requests to help@eecs and staff will make them for you.

EECS Web Servers Maintenance, Aug 11, 9pm

by

New versions of Apache and mod_ssl will be installed tonight, August 11, 2009, on the following servers:

* www.eecs.berkeley.edu
* www.cs.berkeley.edu
* lists.eecs.berkeley.edu
* iris.eecs.berkeley.edu


This will require a quick restart of each web server. Brief outages (less than 5 minutes) will be seen between 9:00pm and 9:30pm.

Department website, mailing lists, jabber offline

by

The department’s web server (www.eecs & www.cs), mailing list server (lists.eecs), and jabber server (jabber.eecs) all run on a Xen virtual cluster. After last night’s network failure was resolved around 2:30am, the Xen cluster failed to recover gracefully. These services had to be manually restarted this morning. Web and mailing list services were restored around 9:20am, and jabber was restored around 9:45am.

Staff are investigating why this occurred and how to prevent it from happening again.

Brief Downtime for Multiple IRIS Services

by

The EECS Department website, FTP server, Windows Terminal Server (winterm), the IRIS website, Jabber, and Sympa (mailing list) services will all experience brief periods of unavailability beginning at 7:00am on Wednesday, February 25, 2009, possibly lasting until 8:00am.

The servers hosting these services will be changing IP addresses during this time as their current subnet (128.32.139.0/24) is being repurposed. DNS will be updated at 7:00am as well, so you shouldn’t need to make any changes to client applications unless you’ve been accessing any of these services directly by their IP rather than by their DNS name.

Mailing List maintenance, Friday, Jan 23, 6pm

by

The Department’s mailing list server, lists.eecs.berkeley.edu, will be shutdown, upgraded and restarted starting at 6pm tonight. Mail sent to department mailing lists will be delayed during the outage, which is not expected to last longer than 15 minutes. The lists.eecs web interface will also be unavailable during this time.

A minor upgrade to the mailing list software was recently released which fixes a bug that was introduced in the previous version. Some of our mailing lists were affected by this bug, so we are upgrading with short notice.

The upgrade has been applied to a test server with no issues, and we expect the total downtime to be less than 5 minutes.

[Actual downtime was 7:17pm – 7:18pm.]

Mailing Lists Maintenance, Sunday, Jan 4th, 10pm

by

The Department’s mailing list server, lists.eecs.berkeley.edu, will be offline beginning at 10pm for maintenance. The mailing list software will be upgraded to Sympa 5.4.4. This is a minor upgrade which consists of numerous bug fixes.

Service should resume no later than 11pm, probably much sooner.

During the outage, any mail sent to a department mailing list will be held for delivery. All mail will be delivered when the maintenance is completed.

Multiple Services Offline for About Eight Hours

by

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.
