It's so true. The entertainment/consumer shopping industries seems to have surpassed banks/governments in availability. It's also pretty ridiculous knowing that some of these companies are tasked with keeping our data/money safe, and yet they still don't allow extremely complex passwords. |

In the end, one system needs to be responsible for a given account... best case you could have is only some accounts/users are affected. It's a different kind of problem.
Facebook, for example uses Cassandra with a very wide distribution of nodes, with an immediate ack on receive... you can't do that with a bank... transactional payment systems won't tolerate it. You could do a few things to alleviate this issue... read-only replicas, etc... even then it's a matter of failing soft (disabling only those systems/services that are unavailable instead of the whole thing).
