I have similar problem recently.
Ejaz,
I think your server can resolve the domain name correctly because it's
resolv.conf set to a public dns server, try to resolve by itself and see
what happen.
About two month ago, my dns server have the similar problem on some
domains, like cdn.sstatic.net, ecx.images-amazon.com and arduino.cc
etc.. The nslookup will get "timeout" and bind debug log shows "host
unreachable".
here is part of bind error log:
