I used Network-Tools.com to traceroute to curtin.edu.au. Details are below:
134.7.179.56 is from Australia(AU) in region Oceana

Trace complete
Looks like a lot of gibberish to me and it doesn't make it easy when it is formatted like the text above. But basically there are 6 columns. The first column which is numbered from 1-18 are the number of hops it has taken to get from my destination to the Curtin server. It took 18!
The next 3 columns are the responses from the router and how long it took (in milliseconds). Each hop is tested 3 times. Where it says "Timed out" there was no response from the router so it tried a different router.
The fifth and sixth columns are the IP Address and Host Name of the routers we had to pass through to get to the Curtin server.
Using the 3 millisecond figures for the last traceroute, the average time in milliseconds from the tools site to the Curtin server was 298ms.
I then tried to Ping the Curtin website using Network-Tools.com. Details are below:

Interestingly, both traceroute and pinging took about the same time to locate the server. Traceroute seems to supply more information as to what servers it has passed to get to the destination so may be a more reliable.
The IP number for the Curtin server is 134.7.179.56
I also downloaded A-ToolBar from the Tucows website (http://www.tucows.com/preview/323577) and tried pinging the Curtin server and it pinged it in 5 hops. I then tried to trace cutin.edu.au using A-ToolBar and it only took 1 hop. I'm not sure if this result is correct so it is worthwhile to try out different applications as you may get different resuls.
They are both quite handy tools if you had a website hosted externally and you were unable to access it. Using both of these tools you would be able to find the exact place where the connection is dropping out.
Below is a screen shot of A-ToolBar when I pinged the Curin server in 5 hops:
What is Traceroute ...?
traceroute is a computer network tool used to determine the route taken by packets across an IP network.

Still confused? Me too!
Traceroute is a command which can show you the path a packet of information takes from your computer to one you specify. It will list all the routers it passes through until it reaches its destination, or fails to and is discarded. In addition to this, it will tell you how long each 'hop' from router to router takes.

What is Ping ...?
Ping (Ping referred as Packet Internet Grouper) is a computer network tool used to test whether a particular host is reachable across an IP network; it is also used to self test the network interface card of the computer, or as a speed test. It works by sending ICMP “echo request” packets to the target host and listening for ICMP “echo response” replies. Ping measures the round-trip time[1] and records any packet loss, and prints when finished a statistical summary of the echo response packets received, the minimum, mean, max and in some versions the standard deviation of the round trip time.
