Update : Amazon Route 53 Traffic Flow Announces Support For Geoproximity Routing With Traffic Biasing

If you’re using Route 53 traffic flow, you can now use geoproximity routing, which lets you route traffic based on the physical distance between your users and your resources. You can also route more or less traffic to each resource by specifying a positive or negative bias.
