The internet should have a plan B

[Walking Void]

Might You be suggesting that internet across the globe simply ceases? What would cause this? My suggestions are at a ludicrous planetary scale: aliens attack, or countries deploy massive EMP weaponry, or a cosmic body happens to enter too close to earth causing a catastrophe in the scope of electromagnetism.

And the internet is unlikely to fall altogether, after all, DNS servers are spread throughout the world. The internet is not centralized anywhere.
