Remember that a number of ISP's 'core' routers are going to have ICMP
rate limits in place when one of their interfaces is the target. While
you may see high packet loss across an ISP link, unless you are getting
similar numbers from all hops past that point you aren't looking at real
packet loss, since the transit packets are getting through fine. It's
just the routers themselves that are ignoring requests or discarding
responses in favor of pushing routed packets.
