Yes, an interesting question you asked in many developing countries there are problems with electricity supply, it is often disconnected without warning in this case it is necessary to purchase a diesel generator of electricity in order not to depend on a centralized supply of electricity.
but if there is an automatic power outage the Internet network will weaken because some may not work well because of lack of electrical energy to be able to run it, so if you use diesel power generator, can make sure the internet connection you use will be slightly disturbed even will run long enough to be able to access anything,
