Here is the result:<br><br>--------------------------------------------<br><div>C:\TraceTCP traceroute for Windows\tracetcp-0.99.4beta>tracetcp ec2-184-72-17-255.us-west-1.compute.amazonaws.com:22</div>

I guess it's round trip?<br><br>And yep, it sounds like hell. I was trying to find a way to figure out if accessing an instance of EC2 in Singapore is faster than in the US and I thought about using traceroute... I end up by spending way too much time on
