Hop 13 and 14 clearly show 0% loss. That means 0% loss from blizzard’s server’s to our core and Vumatel handover in Cape Town. I can’t see what happens beyond this point because your router’s ICMP is disabled. Just to be 100% clear, there is 0 loss between blizzard and our network according to these results. If you see loss on Intermediate hops, that’s because those devices may not respond to ICMP requests. But seeing as it does not carry through to the last visible hop, this MTR is clear.
