Abstract

Systems and methods for publishing and using images of domain name system (DNS) zone configurations are described. An image file containing a copy of some or all of the DNS records associated with a zone DNS server (e.g., a DNS server for a zone) may be stored in a repository. In response to detecting that the zone DNS server is unavailable, an image server system retrieves the image file and stores the image file in an image DNS server. The image server system notifies a higher-level DNS server that the image DNS server is a DNS server for the zone. In some examples, the image file includes a zone signing key (ZSK) associated with the image DNS server that is signed by a key signing key (KSK) associated with the zone DNS server. The image DNS server uses the signed ZSK to sign DNS records for subsequent authentication.
