Problem connecting to American Websites via TelstraClear

This was one of the most annoying problems I've ever had. Half of the usual websites were not opening properly in any of my browsers. sites like Yahoo mail, Facebook, eBay, Youtube were all getting partially loaded. After a long run around and trying all sorts of remedies suggested on the Web such as disabling all Add-ons, host firewall, clearing caches etc, I finally figured what the problem was and though it's best to share it before I forget:
The problem arises when you are accessing a cache accelerated website (such as those above) and going through a transparent proxy of your Internet Service Provider (TelstraClear in this case). Apparently if you don't use the same set of DNS resolvers as the Transparent Proxy the two nodes (your PC and the Proxy) will end up with different target hosts, hence not receiving a page properly.
To fix it, you simply need to make sure you are using your ISP's DNS servers and not any other ones like Google's or OpenDNS.
