Though of course then the trouble is, if AWS is simulating specific behaviour, it won't be exactly the same as real problems when they occur. It is a bit better, but hard to say how much better.

I'd think the key on this is being able to simulate very specific partial-failure conditions. e.g. specific packet loss, loss of connections to EBS, etc. Just turning machines off I expect wouldn't be that valuable.

If Amazon simulated power failure, or network cable disconnect, or potentially even corrupt writes to disk, I personally feel it would be indistinguishable from the event really happening.

The problem is that they can't really realistically simulate that for a single instance unless you've got the whole physical machine to yourself, and of course the worst issues tend to be when it's half-broken, not entirely off/disconnected

Power loss or network disconnect could easily be simulated without needing the whole physical machine.
