For each ping sent to www.cern.ch from pinger.slac.stanford.edu or ping.desy.de, perfsonar-unimas.myren.net.my (but not from pinger-host.fnal.gov, netmon.physics.carleton.ca) it responds with ~3 pings consistently. Using the normal traceroute www.cern.ch does from SLAC does not respond. Using the ICMP traceroute it does respond (twice). Pinging each node along the route using pingroute.pl (http:/http://www-dev.slac.stanford.edu/cgi-wrap/scriptdoc.pl?name=pingroute.pl) (unfortunately mtr does not report duplicates), it is seen that only www.cern.ch responds with duplicate packets.
