Yesterday 19. February 2019 a hard drive failue caused our main Dashboar server to fail and forcing us to switch to a backup server.
We replaced the defective hard drive right after the incident and during the night it rebuilt the RAID array. To reduce the load during RAID rebuild, we kept everything running on the backup server during the night just in case.
The RAID array has been successfully rebuilt and we have now routed main traffic back to our main server.
