Geolocation routing lets you choose the resources that serve your traffic based on the geographiclocation of your users, meaning the location from which DNS queries originate. For example, youmight want all queries from Africa to be routed to a web server with an IP address of 192.0.2.111. Another possible use is for balancing load across endpoints in a predictable, easy-to-manage way, sothat each user location is consistently routed to the same endpoint. http://docs.aws.amazon.com/Route53/latest/DeveloperGuide/routing-policy.html#routing-policyweighted
