big thank for that but, i am testing that for one day :)
Can you do an AStraceroute or manually translate those addresses into AS#s? That is, might level3 and tinet be using multiple AS#s, in which case this isn't unreasonable?

This is just a guess, but I'll bet the route changed while you were measuring it.
Traceroute sends a request, awaits a response, sends a request, ... Suppose that the route was
172.28.0.1 -> 10.16.0.2 -> 41.200.16.1 -> 172.17.2.25 -> 213.140.58.10 -> 195.22.195.125 -> 4.69.151.13 -> 213.200.68.61 -> somewhere else
and after the test got that far, two systems got inserted into the path before level3, resulting in the route entering level3 at a different point, 4.69.141.249. What you now have is
172.28.0.1 -> 10.16.0.2 -> 41.200.16.1 -> 172.17.2.25 -> 213.140.58.10 -> 195.22.195.125 -> unknown -> unknown -> 4.69.141.249 -> 77.67.66.154 -> and so on
The effect would be to get a result like this.
Next time you see something like this, suggestion: repeat the traceroute and see what you get.
