Hi, @eamcvey, my best guess is that the previous records are sometimes being returned because they are still cached by a DNS resolver. There is more about these issues here:
If you still get these errors, it would be helpful to know the following details to troubleshoot:
the resolver being queried (domain name or IP address)
the DNS record being queried (the domain name and record type)
the answer returned by the DNS resolver
Please let us know if there are other questions and we’ll do our best to answer.
