This can have a variety of reasons - packet-filtering is not the least
I don't think centos.org is just sitting there with no iptables etc.
I can reach centos.org from my colo-box perfectly (via lynx) - but I'm
not sure why I would need 16 or 17 hops to do that - and even 20 for
I can reach our own little website via 8 hops, same as yahoo.de
I should point out that I have no deeper insight into the inner workings
of how internet-routing works - maybe this is all expected.
But in the past, mtr was quite reliable pin-pointing severe problems.
