GeoDNS, is it real and in use?
 

We have moved one of our key websites to amazon's EC2 cloud along with their ELB load balancer solution. The only issue we are a US only company due to international shipping. etc. The old co-lo hosting I had iptable rules with numberous known A classes and they were blocked. Well amazon doesn't push the public requested IP (yet) and their firewall setup is impossible to do this.

My next thought was using GeoDNS (http://www.caraytech.com/geodns/). Then I can say US -> us.conf which has the produciton IP, site, etc. If not, they get badip.conf, which gives them another IP which is simply the same server, different vhost with a sorry we dont ship international.

Sounds good on paper, but wonder if people are using this in a production environment along with .02 good/bad.

Thanks

While there are a lot of places that sue these techniques, I personally don't think they're ready for prime time. I am consistently placed in wrong cities, provinces and even countries depending on the implementation used on some sites.

It is probably easier and less troublesome in the long run to advise in your shipping info that you only ship to US addresses, and perhaps an obvious but tasteful note on your front page that you do not ship internationally at this time.
