Much the same deal it seems with WinMTR... ICMP can only get you so far. Standout seems to be 203.8.177.110 where the latency spikes and the packet loss begins.

I did the right thing and contacted my service provider as well to log a ticket on their end (hello to anyone who might end up with the escalation! :-D )
