As I suspected the average ping from the local computer was less then the ping from the net tools site. My reasoning for this belief was that my local computer was situated much closer to the Curtain university server and thus required less ‘travel time’ and needed to travel through less networks. The one from the net tools site would have had to go through several different networks before reaching the curtain website. I’m under the impression the net tools site is located in the US, thus it would have had to go through its own local network, then through its ISP, then to a server in the US, then a number of servers to reach an Australian server then navigate to the curtain server. A simple trace route confirms this, whereas it was 13 hops to reach the curtain server from the net tools site, it was only 11 hops from the local computer.
