[dns-operations] Enom's name server broken?

[Michele Neylon :: Blacknight]

Surely that's an issue with your resolver and not with enom? Or am I misunderstanding the question .. 

(or maybe I need more coffee)

Or are you expecting eNom to purge DNS records for domains for which they aren't currently authoritative?

Our resolver will cache (depending if it is parent-centric on child-centric) NS records from .com authoritative name server (TTL of 2 days) or Enom's name server (TTL of 1h). Then, we change list of authoritative name server at Enom (here as registrar) and within minutes .com authoritative servers will be updated. However, our resolver will keep asking Enom's name server for our domain. What Enom's server will reply? Let's see:
