your assumptions are horribly off.
first, when a site is without power, I of course want to know that 
before it goes down, just for the fact that then I know the reason why 
it is not reachable. So instead of trying to find where the network 
broke, I can send power people to the site. And I can do that well 
before batteries drain - which gives at least half an hour lead.
And your assumption that I cannot get people within half an hour into 
remote sites looking at the problem and hopefully fixing it is just 
plain wrong in many cases.

I, for one, don't care about UPS controlled shutdows.
I need the data points, to prevent downtime, or at least minimize it.
