A traceroute may not tell what you want.  Unfortunately, many routers
block icmp packets, so a traceroute will stop at that server even though
web traffic goes through it fine.  You might try mptraceroute for
windows, which allows you to specify a different port to run the
traceroute on, or a similar program for Linux/Unix, if there is one.
