On Saturday, June 6th, we will be doing major upgrades to some of our backend systems. This work will start at 10 am. We expect that some of services will start coming back up in about 3 hours, but due to the complexity and extensiveness of the upgrades, the downtime may extend well beyond the 3 hour mark. These upgrades are imperative for the continuing reliability of the infrastructure services. We apologize for the inconvenience.

The following services will be affected:

* Home directories
* Project space
* UNIX SWW
* Departmental/IDSG web servers
* IMAP (due to the additional work, IMAP will be down for an additional 2 hours)
* argus/login (UNIX login servers)
* Department websites www.eecs / www.cs and all hosted project sites
* Department mailing lists hosted on lists.eecs
* buffy and all ACG applications
* wikis hosted on wiki.eecs
* Department’s jabber server, jabber.eecs
