A zone or name server does not have a backup administrator.

| Description |
|---|
| If there is no backup DNS administrator, then there is nobody to assist during a security emergency when the primary administrator is unavailable. In some cases, a backup administrator can also detect problems introduced by the first administrator before these problems are allowed to propagate. Personnel redundancy is as important as technology redundancy for the DNS availability. |

| If the site POC cannot produce a list of backup personnel authorized to administer each zone and name server, then this is a finding. If any zone or name server has only one DNS database administrator or only one DNS software administrator, then this is a finding. If there is not a backup administrator for both roles, then this is a finding. |
