Apologies for the cynicism, but that immediately makes me think of a node owner dropping a tinfoil hat over their node, waiting for an ACK from the technician, then taking it off again and splitting the "repair" money with the technician. Lather rinse repeat. It could even be automated.

You'd just need one crooked technician who can recruit some number of node owners. (If the tech did it via remote-controlled power interruption and only did it on scattered nodes in areas with lots of redundancy, they wouldn't even need to recruit node owners and split the cash. But they'd also be leaving evidence that could easily get them in trouble once someone started getting wise to it.)
