Melkinpaasi, melkinkari and melkki, in that order, will be reinstalled using University's newer Ubuntu 14.04 based Linux version. It will be done one host at a time, so that at least two other hosts will available at any time. I'll attempt to minimize downtime so that a new host will come up as soon as the old one is shut down.

After the update all hosts will by default use University's AD home directory as the default home directory, the same as classroom hosts already do. If you want to use old CS home directory (which is the only place where ssh key based authentication will continue to work) you need to login with a user account user@cs.
