On Wednesday, 7th of April 2010, starting at 6pm and lasting until approximately 9pm, there will be several maintenance downtimes for nearly all of our services due to several software upgrades and relocation of servers.

So if you're using one of our managed workstations or thin clients, or use data residing on group drives, please save all your work and preferably log out/disconnect before Wednesday, 6pm. And even if the services seem back after the first short downtime, don't expect to be able to work again from that point on since we will have several short but also some not so short service downtimes in a row.

Update, 20:30h: Most servers and workstations are back online. Not yet ready for usage are: fatboy, the IDL license server and the Condor master server. They will be back later tonight.

Update, 22:45h: fatboy is back online again. But two infrastructure servers (which haven't been touched by today's maintenance) seem to have hardware issues. Because of that the maintenance of the IDL license server and the Condor master server have been postponed until further notice.

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.
