This is considered multiple unrelated failures. You usually don't want to (at least to start) design a system to handle this.
handle a machine power down? Yes. Handle a network cable unplug? Yes. Handle 1 machine power down and 1 network cable unplug at the same time? That may be impossible to handle, or it may be an order of magnitude harder to handle.
Get all the single failure issues nailed down. Then perhaps you can do a little work on multiple unrelated failures, but it gets insanely complex fast.
