Yes. The sad truth is that modern equipment is generally less forgiving than old kit when it comes to indifferent mains power supplies.
Those guys would be well advised to get to grips (as much as possible) with the power surges, black-outs, brown-outs and interruptions in general.
Failing that, the use of battery-backed equipment and (or) UPS is most likely the way forward.
They may be able to fix these units now ... but what about the next time?
