Description

If the auth responds very slowly and the records expire in between, the capping of TTLs is not enforced for lack of data. This does not happen on regular resolve as then then the

child records are used immediately if not expired and thus valid, or the

records are expired, and in that case not used. So this case

can only happen if almost expired records are used to refresh the

authoritative NS records.
