It depends on how serious it was ...local isolated ? or a major grid grinder ?...
Life as some folks know would probably change in a very big way ..not for the better ...
Hospitals may have back up electrically .Even then for how long ? and who gets to get helped ?
Socially it would be a disaster in a large metropolitan city. No electricity , no way too communicate easily unless you have a hand crank radio to hear who else is effected in the scheme of GEO .
No more fresh water , no more food delivery's , no more transportation structure .
If you are an average Joe or Jane and choose to hoof it your status in the human food chain has just been reassigned to Prey .
Of course we all know that law enforcement and large agency's Like The Friends w Benefits agency that wanted to crack the Apple Phone will have some sort of mobility ...

I have been exposed to riots and I can tell you fist hand there is no such thing as having a friend anymore ...
My dog will probably get shot for food unless I'm a quicker draw .....
Seen this personally ...large groups of people will loot and do things they would never dream of doing ...
Organized gangs will make a power play and try to take control of resources ...food warehouses and storage facilitys...
The average citizen will be under siege from all ends of the opposing social elements .
Getting the squeeze from the Bad guys and the ummm bad guys that are supposed to be the good guys

say aren't they supposed to be following orders ....
Who's giving them? that's what worries me ...
I have said enough ...that is only the tip of the iceberg ...
