It is certainly possible we're seeing different things from the places
we're sitting. But the real question isn't whether they _connect_ on
opposite ends of a continent or ocean, but whether they need to announce
a globally visible route in both locations. This is only absolutely
necessary if they prefer traffic to flow over their internal network
rather than over an ISP network. It is also desireable for backup
purposes but I feel this isn't an important enough reason to allow it.
