thats a rather high hop count to get that far. I see...
$ traceroute www.centos.org
traceroute to www.centos.org (72.232.194.162), 30 hops max, 40 byte packets

which is only 8 hops to that same LosAngeles1 gateway.
anyways, I never have any problems seeing it, so my guess is, your
problem is in the first 15 hops you didn't show.
btw, the traceroute worked from my host using both -I and -T (icmp and
tcp respectively) traces.
