I'm not sure how closely DNS requests correlate to bandwidth demand/consumption. Certainly there are many clients that do a single DNS query on startup / initiate and keep querying the same IP from then on. It might balance out over time, I don't have enough data to make an assertion :-) > servers.

A backup pool with enough resources is a good idea, I'd be happy to have an option to nominate servers outside of a region as available as extra capacity for that region, otherwise the larger regional or global pool would be a better option.
