hi guys and gals
One strange scenario that happens is that when I ping and traceroute to a
destination 202.161.128.202 from internet :
It shows high latency times between the last 2 hops :

However when I do a ping and traceroute on my second last router it shows
healthy ping times between this router and the destination
Router>ping 202.161.128.202
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 202.161.128.202, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 580/583/584 ms
Router>trace 202.161.128.202
Type escape sequence to abort.

Why is this so and is there really a latency problem and if so at which
point is latency at ?
thanks
