Blog from March, 2012

On Thursday 29 March 2012 between 07:00 and 08:00 local Bremen time servers and network components will be updated.

Server and network operations will be unreliable. Expect unavailable servers and sudden downtimes of services without prior explicit announcement.

If you have to work on files stored on the server during that time, then before the maintenance hour copy the respective files to your local hard disk, work on it locally, and after finishing your work and after the end of the maintenance interval, copy them back onto the server.

For more details on the maintenance hours see the Maintenance Hours page.
