Of course, Amazon is a US company, so with the proper subpoena from a US court AWS technicians will [have to] deliver images of the virtual servers and/or remove them and/or modify them or whatever else is requested, without the right to inform the customer if the subpoena says so.
Wouldn't the system see a raid's confiscation of a server as just a down machine and do the normal thing to bring up a new server to handle the load correctly? "Okay boys, now go get that server. Wait, now that one, now that one"
