All nameservers unresponsive when master is down

[Sam Pointer]

Thankyou all for your time.

Peter, your diagnosis would seem to indicate that a networking/connectivity
error is at fault rather than an actual BIND/DNS problem. I'll try and
ensure that this ns2/ns4 is routable from the world before I proceed with
anything else.

Thankyou all for your help and time.

Well, you may *think* this is the case, but have you actually verified
it from outside your network? They look pretty unresponsive to me:

ocelot[~]$ dig @ns4.hpdsc.com hpdsc.com ns

; <<>> DiG 8.3 <<>> @ns4.hpdsc.com hpdsc.com ns
; (1 server found)
;; res options: init recurs defnam dnsrch
;; res_nsend to server ns4.hpdsc.com  195.167.246.4: Operation timed out
ocelot[~]$ dig @ns3.hpdsc.com hpdsc.com ns

; <<>> DiG 8.3 <<>> @ns3.hpdsc.com hpdsc.com ns
; (1 server found)
;; res options: init recurs defnam dnsrch
;; res_nsend to server ns3.hpdsc.com  195.167.246.3: Operation timed out
ocelot[~]$

I'm thinking your time would be well-spent talkint to your provider or
examining any packet filtering rules that you may have in place. Your
second machine is not responding to queries.
