* www.eecs.berkeley.edu
* www.cs.berkeley.edu

IRIS website offline unexpectedly

by

The IRIS website went offline unexpectedly around 11:06pm Friday, July 17th. I was trying to debug a problem with the firewall when all access to the internet was interrupted.

Service was restored around midnight.

My apologies for the outage.

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.

IRIS Website maintenance, 5pm tonight

by

A new version of the IRIS Roster and Network applications will be deployed tonight at 5pm. These applications will be unstable between 5:00 and 5:15pm while the code is upgraded and the server restarted.

This new version fixes the problems that were introduced on March 30 when we migrated our database to a new server. Some change we made at that time caused the version of PHP we were running to start crashing sporadically. We have spent the last two weeks updating our code to work with the latest version of PHP, and it is now stable again.

I apologize for the recent problems, and thank everyone for their patience during this troublesome upgrade.

IRIS Website Maintenance, 5-8pm, March 30

by

The IRIS website will be unavailable Monday, March 30th from 5pm to 8pm while undergoing maintenance.

The databases used by many of the applications found on the IRIS website are being migrated to a new server, now hosted by IST. This downtime is needed to copy the data over and update our applications to use the new server.

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.]

Printer server problem

by

The EECS Department’s print server, print.eecs.berkeley.edu, was working intermittently between 10:30 and 11:30am today. After several attempts to restart the print service, the entire machine was rebooted at 11:30, which resolved the problem.

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.
