Fortunatly we are moving away from the state the 6bone used to have ;)

Unfortunatly though the contact(s) for certain AS's in the above path
apparently aren't reachable per email :(
Though I suspect that the routers doing this are not that stable at
all, either they crash or they get reset once in a while as sometimes
mysterically the ghosts vanish.

More about these ghosts can be found on http://www.sixxs.net/tools/grh/

Indeed, the smart people filter out those bogusly long ASpaths.
