The EECS Department’s [jabber server](https://iris.eecs.berkeley.edu/15-faq/35-unsupported/04-jabber.html) is being upgraded to the latest version [(OpenFire 3.5.0)](http://www.igniterealtime.org/projects/openfire/index.jsp). After the upgrade, the server will be restarted at 10pm on Wednesday, April 16. At that time, any open IM sessions or chat rooms will be temporarily disconnected. Total downtime should be less than 5 minutes.
Also, it has been reported and confirmed that Google Talk users cannot be seen by or send messages to users of the EECS Department’s Jabber server. This problem appears to have started recently. It is hoped that the server restart will be enough to fix this issue, but if the problem persists after the upgrade we will investigate further. Check [the IRIS website](https://iris.eecs.berkeley.edu) for updates.
