Server UNICORN is down, since it seems that the main boot disk had failed unexpectedly. We have already alerted the datacenter to replace the drive, however technical support on Sundays is always little bit slow at the datacenter. As soon as the disk is replaced, we will need to reinstall the OS on the server, and restore user accounts from our backups.
UPDATE1 - 12:01PM - Disk is replaced, we are proceeding with reinstalling the OS
UPDATE2 - 14:45PM - Server is up and running, we are making some final configuration
