Abstract
In one embodiment, a zone resiliency application indicates that an authoritative name server is in a degraded state. In operation, the zone resiliency application determines that the authoritative name server is in a degraded state. The zone resiliency application then generates a status record that indicates the degraded state. Subsequently, the zone resiliency application associates the status record with a domain name service (DNS) response to a DNS query. The zone resiliency application then transmits the DNS response and the associated status record to a requester.
