What are the possibilities of two master servers operating in parallel?
IMO this is a little like putting all your eggs in one basket. I know its not really a major thing, and is very rare, but it can't be good for business.

At least with tandem or parallel master servers you have some sort of safeguard for any bigger power-outs or whatever in the future.
Anyway, just a thought.
