Hurricane Electric packet loss

Hello,

Did you notice the average RTT delay from the 5th hop and beyond? I'm 
not sure if you can trust the values according to the high packet loss, 
but it may indicate an additional problem (or MAY confirm your 
assumption about congestion).

Without knowledge of their network I am unsure what’s the cause of it but we’ve seen it on the Tokyo - US routes as well as the London - US routes. It reminds me of the Cogent expansion which was carried out by unsustainable oversubscription which eventually resulted in unusable service for a number of years. Having seen some of the rates that HE has been selling for I can’t help but wonder if they made the same mistake ...
