A little bit of devil advocate here. If the server rack was full of virtual hosting that would mean one server could ideally host multiple websites and if all the servers shared 1 or 2 SAN's it would be difficult from an outsider looking in to know which server hosted what website especially with Graveyard shift. Even if you knew node 1 server hosted the site it would still be shared on the SAN and could easily be started on another server.
