LDAP High-Availability Testing Wednesday 10pm

by

We are upgrading our [LDAP infrastructure](https://iris.eecs.berkeley.edu/news/10933-department-ldap-upgrade-thu-jan) to replace an old server with a new machine. This server is a backup node which should take over the role of the LDAP server if the primary server fails. In order to ensure the new server is performing as expected, we will be simulating a failure of the primary node at 10pm on Wednesday, June 17th. The backup node should take over within 5 seconds. If all goes as planned, we will then bring the primary back up and call it a successful test.

During this testing, there will be brief (~5 second) interruptions in LDAP service. This will occur at least twice but possibly more if the first test is unsuccessful. During those brief intervals, anyone whose timing is especially good might notice trouble logging into any application that uses LDAP.

All testing will be over by 10:30pm at the latest, but probably much sooner.

Brief outage to numerous services Monday June 1

by

Between 7pm and 8pm on Monday, June 1, we will be patching and rebooting the following servers.

www.eecs, jabber.eecs, iris.eecs, lists.eecs, apps.eecs and wiki.eecs.

Recent operating system patches include a new kernel, which requires a reboot to install. No machine will be down for more than 10 minutes.

The department’s jabber/xmpp server jabber.eecs.berkeley.edu will be unavailable for approximately 30 minutes on April 29th, beginning at 6pm.

During this maintenance, the [Openfire](http://www.igniterealtime.org/projects/openfire/index.jsp) server software will be upgraded to version 3.10.0. The [changelog is available on the igniterealtime website](http://www.igniterealtime.org/builds/openfire/docs/latest/changelog.html).

Department Webserver Upgrade, April 28th

by

On April 28, 2015, the department webserver www.eecs.berkeley.edu (and www.cs.berkeley.edu, as well as all the project websites that IRIS hosts) will be migrated to new, faster hardware. As part of this upgrade, we will also be upgrading the version of the Apache HTTP server software to the current branch, Apache 2.4. This is considered the current best version and contains [numerous improvements over the 2.2 branch we are currently running](http://httpd.apache.org/docs/2.4/new_features_2_4.html).

Unfortunately, [there are some changes in syntax or behavior](http://httpd.apache.org/docs/2.4/upgrading.html) that will affect people who have their own websites. The owners of any web site which may be affected by this change will receive a direct email later today with the subject “Action Needed: Update your .htaccess files.” This email will list the specific file(s) you need to check and will include a link to some documentation on the most common changes that will be needed.

This documentation is now [up on our website](https://iris.eecs.berkeley.edu//10-services/web-technotes.html#upgrade24) .
