If you are looking to do some traffic steering, geodns is a great tool, if you are willing to either run your own authoritative DNS servers, or farm it out to a service that supports this, such as aws route53. I pretty busy right now, but I may have some time at some point to help spin up authoritative servers based on preferably knot, or pdns.
