A security-update on one of our clusters failed unexpectedly and caused a downtime of our authentication server and printer server which needed manual intervention. All services should be back again by now. We apologize for the inconvenience caused by this. Update 18:00: The thin clients work again, too.

There will be a short maintenance downtime of our authentication server this evening at 7pm. This means that you won’t be able to log in to any managed D-PHYS workstation or D-PHYS service for about 5 minutes. Update 19:01: Maintenance successfully over.
On Tuesday, the 2nd of December 2008, beginning at 6pm, we will migrate the services on our current authentication server to our high-availability cluster. During the migration you will not be able to login on any of our managed workstations, home and group drives or web services. Existing login sessions on workstations should survive the downtime, but it is usually better if you log out before migration. Additionally, *.dhcp.phys.ethz.ch dynamic hostnames will not work either.
Update, 22:30: Migration done. Everything should be back to normal.
Update, Wed Dec 03, 09:30: We found and corrected a problem with the web browser proxy.pac.
