When the hardware is outsourced how would you propose testing the 
non-software components?  They do simulate availability zone issues (and 
AZ is as close as you get to controlling which internal power/network/etc 
grid you're attached to).

I suppose they could introduce artificial network latency/loss @ each 
instance - and could add testing around what happens when amazon's API 
disappears (as was the case friday).

Beyond that....the rest of it is up to the hardware provider (Amazon, in 
this case).

..david (who also relies on outsourced hardware these days)
