Problems for route to 92.43.96.0/21 for Comcast?

2013-02-11 Thread Jim Burwell 
Can't seem to get to 92.43.96.0/21 (specifically 92.43.96.130 ... in
Salzburg Austria) from Comcast Business in the Bay Area (traceroute
stops close to provider edge).

Works from Verizon FiOS down in LA, and a HE.net host in Fremont.

Comcast folks may want to look at this.  :-)

Can you provide a traceroute showing the failure? I just traced to it from
my desktop inside Comcast and the trace died eleven hops after leaving our
network. If your trace dies inside our network, I'll get that info to the
right group to deal with it.

Thanks,
John

Comcast has a route server at route-server.newyork.ny.ibone.comcast.net.  From 
the view there, it appears 92.43.96.130 has been black holed.  The IP holder 
and/or folks at AS49322 may want to contact Comcast Security folks.
