I am not familiar with load balancing/backup via DNS. Now that it is hard to
get multi-homed domains, I would think there would be plenty of scripts out
there to do some load balancing, and redirecting if an Internet link goes
down.

Does anyone know a way to get bind to switch ip's it gives out? In the past
I heard a lot about round robin and lowest load. I just don't know where to
look to implement it. Let alone a way to get it to redirect when a link goes
down.
