If a machine is down (as in the machines themselves are dead) then you absolutely need to move the data onto another node to avoid losing it entirely. There is no way to avoid this, whatever your consistency model. If there is a network partition, however, there is no need to move the data since it will eventually recover; moving it would likely make the situation worse. Cassandra never does this, and operators should never ask it to. If you have severe enough network partitions to isolate all of your nodes from all of its peers, there is no database that can work safely, regardless of data shuffling or consistency model.
