How to manage the risk of wide range electronics outage?
With the ease and convenience of integrating hardware with computers, we tend to use computers and electronics for our critical systems.
However, there are many things that can happen to electronics -- from global electromagnetic storms (like the 1859 solar storm) to computer viruses.
One such mishap causing an outage of all electronics in a geographical region could potentially cause extremely large damage. Ideas how to avoid or mitigate, and risk analysis in the comments are welcome.
