We were also worried that propagation of new DNS entries will take a while. But as you've said, there would indeed be tradeoffs. The alternative would be to purchase application-specific load balancers -- not really a far out idea as we were contemplating this, but we want to make the costs as minimal as possible. Multihomed DNS is the way to go, then? Guess we'd have to ask for an increase in IP address allocation. How about my other idea (one IP block routable through both links -- no need to change DNS, etc.)? Is this feasible? Thanks. -- Ian Dexter R.
