TraceRoute to Microsoft's Servers

This is an example of a traceroute to a domain that has disabled the response to traceroute and ping commands at their firewall.

I used an online tracerotue tool located at http://www.infosyssec.com/infosyssec/ipsectools.htm.
When I trace route to their servers, I get:
