EWU identifiers are required to eliminate the occurrence of duplicate values that will interrupt and delay the processes of disaster recovery, high availability, and virtualization.

Designing these resources with EWU values eliminates the possibility of conflict during automated or manual fail-overs, high-availability operations, and disaster-recovery testing or implementation.

That leaves large parts of the market in limbo, producing enough cash from tenants for owners to stay alive and lenders to forbear but with little prospect of an immediate recovery in values.
