Buy a diesel powered generator
Use multiple upstreams
Spare switches/routers
Given enough £££ you can answer any of those problems
Of course you could use a GeoThermal powered generator in case the supply
of diesel drys up.

A good start...
But what if you loose your local network?
Or your local power supply?
Or your internet connection?
I don't see the use of investing time and funds in this kind of redundancy
when your network is a single point of failure.
It will take your availability up a bit, but you'll still have lots of
points on which operation could break.
