non-recursive request to forwarders

So it boils down to;

"My connectivity isn't very reliable, can I steal bandwidth and
resource from people with more reliable connectivity?"

Well the answer is you can't easily, if they monitor who is
issuing recursive queries, they will see you, if you issue
non-recursive queries the answers will be incomplete and not
authoritative, and probably show up just as much if not more in
server monitoring.

Probably the best bet is to ask if you can slave the UA zone,
then you'll have all the UA delegation information to hand for
35 days at a stretch.

Off the top of my head, I think whether the UA domain has glue
is irrelevant if the route to the IP is unreachable. The only
server in the Ukraine (at a guess, maybe kolo?) for UA is
ns.lucky.net, things should work if you ensure you have good
connectivity to these people..... Who is responsible for your
peering?

lucky.net has some minor DNS issues that could do with fixing
for someone hosting a TLD.

Oh and a UA oddity, ns.kolo.net doesn't offer recursion, but
still returns additional data from cache, given it appears to
have a fair chunk of data cached, probably a bad move, but not
as bad as offering recursion.

I'm sure there is more grit in the cogs if ones looks for it.
