As indicated in ALI 3942, an interruption of electrical power is
 scheduled for the weekend Feb 26-27. On the Linux cluster, additional
 maintenance measures will also be required. Therefore, the cluster will
 be unavailable for user operation between
         Friday, February 25, 17:00 and Tuesday, March 1, 18:00         
 All running batch jobs will be removed from the systems; we will leave
 the queues open until Friday 16:00, but recommend to set a user hold on
 any queued jobs which do not start execution in time to complete by
 Friday afternoon.
 Note: A job can be put into user hold by issuing the command
 qalter -h u <job id>
 Once the cluster has been returned to operation, you need to explicitly
 remove the hold again with
 qrls -h u <job id>

 This information is also available on our web server
