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. -- MailScanner is like deodorant...
