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.
