We are offering this kind of service, too (touching cables ;-) ...) and 
we are held reliable for anything that happens while we are in that 
server room.

Of course this happens, but if someone has to work on something in a 
sensitive network, he/she _should_ be aware of the danger and _should_ 
have prepared the rest of the world to be on service at least while the 
work is in progress (please note the emphasized "should"'s)

So if someone shows the guy how many years he needs to work to cover a 
possible damage, this very often helps to ensure that he pays attention.

In this specific case a second monster is there to take over if things 
really go badly wrong.
