The resource is removed from Whois when it is revoked.

OK, when ARIN suspends DNS service it removes the nameserver record in 
the Whois entry, that works for me.  When I read suspend DNS, I was 
think only breaking the glue records, as long as the Whois nameserver 
records are removed too, then we are good.

Maybe with a wildcard returning "Suspended.DNS.ARIN.net" as the PTR record for all recursive look-ups for resources that have the DNS suspended.  This provides in-band feed back and feedback through Whois in the nameserver field.

Yea, after thinking about it more that's not a good idea at all.

>> A final option, ARIN could simply publish a list of resource for which it has suspended DNS.  This is my least preferred option, it is out-of band and I have to go look someplace else then Whois.  But it might be a good stop-gap solution allowing ARIN time to implement one or both of the above solutions.

>> Breaking DNS in a way that is invisible to third parties is not good operational practice.  In this case the cure might be worse then the disease.  So find a way to operationally signal that DNS has been suspended then I'll support the proposal.  This might not require any change to the policy text itself, this may simply need to be an implementation note in the rationale.

I was missing the idea that the nameserver record would be removed and 
part of suspending DNS service.  And yes it is an operational matter, 
but it does matter.

Maybe that could be noted in the rational that the Whois nameserver 
record should be cleared as part of suspending DNS service.
