Is your network multicast enabled ? My traceroute to you shows
that you home to AS 2548, which is.
If so, this might be connected to the RAMEN worm. This is hosing up
native multicast
but good, so much so that it is affecting routers and causing some
unicast problems. I heard, for
example, that it is causing 4% packet loss at the Abilene NOC. RAMEN is
(for the multicast enabled
part of the Internet) effectively a DOS attack.
