I recently learnt that the Internet backbone is made up of a ocean-bottom network of 400-odd fiber cables joining continents.
It makes me nervous that a terrorist attack of any other cyber-warfare or natural cataclysm may seriously disrupt our Internet.
I sometimes wonder if there's any relatively cheap and not hard to learn fallback to have at home, such as a ham-radio system (but that would be a burden if I don't ever use it). Even more alarming is that landline phones are now connected to the ISP as well, so these new landlines our ISP installs in our homes won't work if either electricity or internet goes off.
I wonder if there're any online websites or resources on this.
Any opinions much appreciated.
