Domain Connect is a publicly available standard that enables domain name service (DNS) providers to provide a mechanism for other entities to place or update DNS records on the domain. In the terminology of the CAP theorem, DNS retains availability and partition-tolerance (AP) while dropping consistency. In particular, DNS drops strong consistency for eventual consistency. This disclosure describes techniques to enable the Domain Connect specification to mitigate the effects of eventual consistency of DNS records. The techniques function under various scenarios, e.g., if the _domainconnect TXT record for a new or transferred domain hasn’t been propagated or is malformed.
