Hello all,

I am running Bind 9.7.1-p2 as recursive dns. I encountered this problem with
the domain When I dig, it gives me a connection
timed out response.


; <<>> DiG 9.7.1-P2 <<>>
;; global options: +cmd
;; connection timed out; no servers could be reached

But when I cleared my cache thru rndc flush, I then have a response and
solved the problem:


; <<>> DiG 9.7.1-P2 <<>>
;; global options: +cmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 10733

I digged further about the problem as to what causes it. I found out that if
I clear the cache and then dig first the ns record(s) of, before I
dig, I will be able to replicate the problem.

What bothered me is what is in that blocks the response from Please I need your inputs.
