Wake up call
This has to be treated as a "wake up call". Imagine the chaos that will ensue if the Internet gets totally screwed or even partially screwed. Not only no credit cards but no just in time transport to feed us all and loads of zombies staggering helplessly round the streets smashing their heads against their dark fondleslabs!!!
Large systems like Visa become single points of failure for society, the impact from being unavailable is profound. Its a fools paradise to think you can prevent this sort of event from happening again. Imagine a scenario where all the under sea fibre cables are snipped by a not so friendly submarine, what about all the Internet Of Things going dark, all the lost services from AWS, Google and others. Me? I'm off to Mars on a BFR :-)
