Not all routers respond to the icmp packets in these tests. The fact that the
trace gets beyond that router is usually enough to imply that the packets get
through. I also see the 100% loss at that router, but have no problem with the
centos site.

Sometimes routers are configured to ignore tests like this all the time, and
sometimes they will drop any unnecessary test packets if they are running near
their maximum load. The tests are not a go / no go test.
