Few things, There are limits on how long you can keep your generators running without causing mechanical damage - hence two generators. Redundant power company only charges for usage, there is a small recurring fee for connectivity. If Power goes out from one provider, online UPS kicks in - we switch to secondary power-company if there is a long downtime.This happens about 4-5 times a year - longest blackout was 12 hours to the best of my recollection. When you provide internet service for SME, Banks, and some large-scale corps - redundancy and SLA plays a huge role. Home users benefit from this too. I probably should have been more clear.
