Option C seems plausible, but I'm not sure if the transactions will be buffered indefinitely. The high availability aspect in Option B is interesting, but I'm not convinced the cluster can automatically update the IP whitelist.

I'm not sure about that. I think the cluster will shut down to preserve data consistency.

I agree with you, Lanie. The cluster has built-in high availability and buffers transactions until unreachable nodes return online.
