Thank you all, for the detailed explanation, I understood as sys admin but
our client will comparing with Google open DNS server.
No, I can't use his DNS server. From ns10.cyberia.net.sa, connection
timed out..
It is one of our VIP customer and complaining that if "I have problem in my
"name servers" when we use open DNS server such as google and several
others, they don't have any issue to resolve their records. Satisfying
customer is become tough.
Only they have problem to resolve the queries when they start using our DNS
ns10.cyberia.net.sa
