The failure of both datacenters at the same time left some of the backup servers in a conflicted state, which could not be resolved by the internal IT department or Atos. Zerto was contacted to troubleshoot and identified a workaround for the affected server groups. The solution was a time-consuming manual process of extracting and copying files. The outage also revealed problems with the level of technical knowledge required for disaster response and recovery. The report noted that Atos staff "required technical direction by DT&I staff when managing system shutdown in Guy's datacenter." ®
