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:
