On Thursday, the 27th of August 2009 around 16:00 we will start upgrading the operating system and the webserver software of our main webserver zwoelfi. This may lead to a downtime of many websites at D-PHYS including www.phys.ethz.ch and isg.phys.ethz.ch. Update 21:20: All services should be back to normal again.

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).
