You'd be better off with an AS-PATH, but just follow the chain... Savvis

call that a routing leak. Doesn't take too much work to guess where 
either. :)

Oh and FYI it is still going on, though the route just changed 4 mins ago:

                    [BGP/170] 00:04:21, localpref 200
                      AS path: 7473 17557 17557 17557 17557 5400 15169 I

Singtel -> Pakistan Telecom -> British Telecom -> Google. AS17557 is 
leaking its BGP table, and AS7473 is not filtering its customer. Bad 
network, bad. No cookie.
