This smells like BS.
Really when has anyone worked at a data centre where they shut down the servers and switch to DR site, so that an electrician could PAT test the servers (or the equivalent).
Also, how the fuck can you "shut down every data centre in every location in the world"
This seems like wishful thinking and someone living in fantasy land.
Having said that, I have seen outsourced contracts making a complete hash of things many many times!
