Today around 0715 we experienced a series of power outages in our water-cooled racks in HIT, leading to a shutdown of our most crucial servers. It took us almost two hours to get the systems up and running again, during which time most of our services were not available.
We apologize for any inconvenience.
Today around 14:20 the D-PHYS network started acting up. After about 20 minutes the problem could be tracked down to a machine running amok. Unfortunately, the terminal server plimpy did not survive the downtime and had to be rebooted at 16:10. We apologize for any inconvenience.
We will upgrade our LTSP server "plimpy" the next Wednesday, 24 June 2009 starting at 7 pm. Please save all your open documents and log out until that time. The machine should be ready again the next morning. You don't have to back up your data on /scratch since we will do that. Find the details on the software changes here.
While performing the upgrade to Debian "lenny" we will switch to a 64 bit kernel since finally also Adobe flash player, the last missing mission-critical app, is now available for 64 bit Linux. Unfortunately Adobe still doesn't ship 64 bit Linux versions of Adobe Reader (formerly Acrobat Reader). You can still fill Adobe Reader PDF forms and even create and edit PDF documents on the Windows RDP Server "ramora" which you can access via the ETH Zurich menu, Microsoft Office (or the full-screen login, see above link).
On Wednesday, April 8, starting around 0730 we will upgrade the RAM in plimpy, our LTSP terminal server. This will cause a downtime of about 5 min and the loss of all open sessions. Please make sure to have all your data saved by Tue evening if you're working on a thin client.
Update Wed 0800: plimpy now has 16 gigs.
We need to move most of the group directories to a bigger fileserver.
This will be done on Thursday, 5. March, between 19:00 and 21:00.
During this time most some of the group directories (windata, macdata, unixdata) will be limited to read-only access, and the others will have a short interruption of availability.
To protect you from losing or corrupting any of your files, we strongly recommend you close all open files on the group directories.
Since we have switched to generic names for our services, the group directories will still be accessible the same way as before, so you don't have to change anything.
Update 20:40: The migration is finished and everything should work again! In case of problems please contact the ISG Helpdesk (3 26 68)
We had a partial DHCP outage this morning because the failover system between our two DHCP servers malfunctioned. The problem is currently solved only preliminarily by disabling the failover system and one of the two servers. To get both DHCP servers working again, we scheduled a DHCP server maintenance for today, Friday, 30th of January 2009, starting at 5pm. There may be short DHCP service outages during the maintenance. This means that initially connecting to the network as well as renewing the DHCP lease of your computer may fail for a few minutes. Update 21:45: The DHCP service is working again including the failover system.

Tomorrow Thursday Jan 8 at 0730 we will upgrade our popular Roundcube webmail solution to a new version. This will cause a downtime of about 30 min. By way of consolation, we will provide a new theme that looks pretty nice. Look out for it in Personal settings -> User preferences -> Interface skin. It's called mvision2.
Update: Thursday 0745 - update done
Currently our printer server "leuggel" is not available. It broke down completely over the weekend. We are currently setting up a temporary replacement. We apologize for the inconvenience.
Update 13:37: The replacement printer server is up and printing is working again on all operating systems.
