There is a backup plan. It's called tethering on att which is costing me $10 per gb.
perhaps a better backup plan would be see about getting DSL . then you would have two connections to ensure business needs.
And since DSL rides regulated POTS copper tends to be more reliable than cable and if close enough be direct to CO line is self powered, significantly backed up, often with generator or one can be gotten before batteries fail.
Cable has no such requirements, and can have as flimsy an infrastructure as they wish.
Telco trunk lines are also pretty heavy duty and many times seen them and poles on the ground but still functioning. Power and cable not.
I have had DSL with my laptop work throughout prolonged power outages (like days), and just had to find a 12V power source for the modem after UPS died. (like car, or other 12v battery)
