Hello, 

mtr packet loss column has no scientific precision and should not be considered. It is not mtr fault but forwarding 
routers have a low priority to respond to ICMP requests. The only way you can prove there is a problem is a end to 
end ping, the regular ping command, not mtr.

(understood, however FYI,) 

Also reproduced the results with pings walking them down the line up to
and including the actual host.   The MTR example provided is simply the
clearest representation of the ping results which show the same.
