Apparently true. The specifics leak from one of our CIDR blocks
was only being made to Bill's peering point ( otherwise known
as MAE-LA or MELEE when first started ;-) ). Being fixed shortly. Thanks 

On the larger question, it would be difficult to find two places
on the net with a  consistent view of the global routing table 
although for trend analysis both MAE East and the Sprint NAP should have
a more of a representative view than MAE-LA.
