API_CreateHostedZone.html
DelegationSetNotAvailable
You can create a hosted zone that has the same name as an existing hosted
zone (example.com is common), but there is a limit to the number of
hosted zones that have the same name. If you get this error, Amazon Route
53 has reached that limit. If you own the domain name and Route 53
generates this error, contact Customer Support.

22. Amazon Route 53 / CreateHostedZone
https://docs.aws.amazon.com/Route53/latest/APIReference/
API_CreateHostedZone.html
Public hosted zone: Two hosted zones that have the same name or that have
a parent/child relationship (example.com and test.example.com) can't have
any common name servers. You tried to create a hosted zone that has the
same name as an existing hosted zone or that's the parent or child of an
existing hosted zone, and you specified a delegation set that shares one
or more name servers with the existing hosted zone. For more information,
see CreateReusableDelegationSet.
