The EECS Department website, FTP server, Windows Terminal Server (winterm), the IRIS website, Jabber, and Sympa (mailing list) services will all experience brief periods of unavailability beginning at 7:00am on Wednesday, February 25, 2009, possibly lasting until 8:00am.

The servers hosting these services will be changing IP addresses during this time as their current subnet (128.32.139.0/24) is being repurposed. DNS will be updated at 7:00am as well, so you shouldn’t need to make any changes to client applications unless you’ve been accessing any of these services directly by their IP rather than by their DNS name.

UPDATE

All services are back online with shiny new IP addresses.

Most were only offline for only a few minutes, though the IRIS website was down a bit longer than expected due to being unable to mount an NFS file system as the filer had cached the server’s previous IP.
