	I can't help but think that you (and others that complain)
	have an odd understanding about "broken"...  For me (and
	I suspect many others), broken means the packets don't get
	there.  Connectivity, even if not what I would consider 
	optimal paths, is better than no connectivity at all.

	and now the two points of interest:

	) mapping an ASN to a specific economy is often a false reading.
	  for a higher confidence metric, it would be useful to see the
	  latency btwn each of the these hops in the AS path.

	) if there are perceived reachability problems between two
	  sites in Germany is it really prudent to complain to everyone
	  that its all the Asians fault that connectivity inside Germany
	  is "broken" (to borrow your term)?  Would AS 25484 and AS 25538
	  be willing to connect up to some neutral place like DEIX and 
	  peer directly over native IPv6?  

	just a couple of observations
