In the past, certain peers have required a unified ASN in order to
exchange traffic. If you're using separate ASNs, they want the regions
treated as separate organizations with regards to routing. (IE, they
want you to effectively run them as separate business units.) I do not
know how much of that is an issue today but it could be a real PITA in
days past. Still, a single ASN in my view is the best choice anyway.
