IRIS website unplanned outage earlier today

December 29, 2014 by Rob McNicholas

The [IRIS website](https://iris.eecs.berkeley.edu) was unreachable Dec 29th from around 2am until around 4pm. A change in configuration was made at 2am to put move all departmental websites behind a load-balancer. A misconfiguration in the balancer was preventing SSL connections from working.

The misconfiguration has been fixed and the site is functioning normally again. My apologies for the inconvenience.

IT Support During Winter 2014 Energy Curtailment

December 11, 2014 by Lars Rohrbach

Due to the Winter Holiday, Energy Curtailment, and New Year’s Holidays, the Berkeley campus is officially closed for the period Wednesday, December 24 to Thursday, January 1st, reopening on Friday, January 2, 2014. Additionally, many staff are expected to be out until Monday, January 5th.

All departmental computing servers will remain on and should be available during the break, but there will be no staff on site to provide any computing support or handle any requests. Automatic monitoring systems will alert staff to critical infrastructure problems, and any such problems will be dealt with on a best-effort basis. IRIS staff will be taking advantage of the holiday to do maintenance on some systems which will result in scattered outages, but any such downtime will be separately announced and posted on the IRIS website.
Of particular note are the previously-announced downtimes for the January 3-4 weekend (Network outage and Power outage).

The IRIS Helpdesk will be closed beginning Tuesday December 23, and will reopen on Monday January 5. Problem reports can be left on the Helpdesk voice mail (510-642-7777) or emailed to help@eecs, but staff may not receive or reply to these messages until January 5.

Requests for new IRIS accounts that are received after 3pm December 22 will be processed on January 5, 2014.

During the break, Instructional labs will be locked, but the main servers will remain online (imail.eecs, inst.eecs, cory.eecs, c199.eecs and fileservice.eecs). Instructional support staff will occasionally monitor inst@eecs email over the break. If you are unable to contact inst@eecs, you can leave a message at 510-643-6141. Please be aware, though, that staff may not be able to respond or reply to messages until January 2.

We recommend that all desktop computers be shutdown during the Energy Curtailment Period. If your Windows computer needs to stay on during the break, we recommend that you check with your system administrator to ensure that Automatic Updates are enabled with the option “Automatically download the updates and install them on the schedule that I specify” with a daily update schedule.

Computing support staff will be monitoring their email when possible, so please use standard email addresses to report any urgent problems. As a reminder:

Instructional Computing Environment: inst@eecs
Research / Staff Computing Environment: help@eecs
Enjoy your holiday break!

Brief Wireless Outage in Cory and SD Halls

December 9, 2014 by Derek Calderon

There was a brief loss of wireless service to Cory and Sutardja Dai Halls due to a bad configuration push, which caused the APs in those buildings to lose contact with the wireless controller. Service has since been restored.

Mathematica License Server Update

November 26, 2014 by Lars Rohrbach

The Berkeley campus has a site license for Mathematica. We strongly encourage Mathematica users to visit the Campus Software Central website for information on obtaining a current version of Mathematica and license.

Mathematica licensing on our own EECS license server will expire November 30, 2014. If you have been using an older version of Matlab with our license server, you can update your licensing configuration to point to the new campus license server. See the IRIS Mathematica FAQ Page for details.

Scheduled Maintenance for Wireless Authentication Services

November 26, 2014 by Derek Calderon

On Wednesday, November 26th at 4-5PM we will be installing updated TLS certificates on our primary wireless authentication (RADIUS) server and on the EECS-Guest web authentication portal. Due system redundancy, no outages are expected, except for a possible brief interruption in EECS-Guest authentication. Existing connections will not be lost, but there may be a short period in which users cannot initiate new connections to EECS-Guest. In this event, we recommend the use of CalVisitor until EECS-Guest is responding again.

Mailing List & Jabber Downtime, Monday 6pm

November 17, 2014 by Rob McNicholas

The Department’s database server will be patched and rebooted Monday, November 17th at 6pm. Total downtime is expected to be less than 15 minutes. Applications that depend on this database will be down during this time. This includes our Jabber/XMPP server, jabber.eecs.berkeley.edu and our mailing list server, lists.eecs.berkeley.edu.

cluster.eecs fileservice unresponsive

November 11, 2014 by Lars Rohrbach

We are seeing a high load on cluster.eecs, resulting in NFS fileservice requests being delayed or failing. This affects all project shares hosted on cluster.eecs, and any services dependent on files there. Notably, this includes many research group websites.

Staff are investigating.
