The really neat thing is that you can do this with any nameserver. Install N nameservers and connect each of them to one of your ISPs. These nameservers are all masters, and all contain different data.If you have several nameservers all pretending to be masters for some zone but offering different responses based on IP locality, predictive performance, or any other criteria, then the name for this is: "broken."
There obviously is a need for an 'official' method to do global load balancing using DNS. Let's face it, people are doing it now on a not so large scale but that is rapidly changing because of the introduction of both hardware and software solutions that (mis)use DNS to overcome it's current limitation. I'm not very interested in the discussion why this behaviour would be broken. It's for more interesting to talk about improving DNS so that there will be room for things like load balancing or dynamic DNS. In such a way that people will not start screaming when they see TTLs of 30 seconds or non-linear behaviour of load balancers. Regards, Stefan
