Messages for Linux Clusters

SCRATCH is now fully online again. While we expect older data that were temporarily inaccessible to be fully available again, data that were created in the last few days before the problems started might be corrupt and need to be renewed from tape archive (if one exists) or recreated. 
There will be a reboot of one servers tomorrow, which however should not impact overall system operation.
