Saw a link to this on ShellCity as a handy tool for checking if you've open ports. But their visual network tracing tool is much more fun. Playing around with it I found a path from my house heading out of Ireland over to America, then bounce back and forth from east to west coasts before finally returning the Europe and eventually the uk where the site I was looking for was located.
The attached screen shot is the longest route I've found yet.
