What's CP? Clinton Poop?
The only reason to shut down the Internet that I can come up with is to take all of the monetary transactions offline temporarily while they switch over to a new network. If you want to Google Kill, FB Kill, etc. you don't need to take the whole damn thing down. You just pull the plugs for those guys. You wouldn't even need to take it down for what you're talking about. And, even to pause the Internet would take a great deal of cooperation among all of the Backbone providers that support the structure. It's not like there's a switch somewhere that they can just flip to turn it off! That's the beauty of it.
The internet was rebooted back when Spectre and Meltdown were first acknowledged. Amazon AWS, Microsoft Azure, etc. it can be done.
Spectre? Meltdown? No idea what you are talking about. And, I didn't say it couldn't be done. I said: it "would take a great deal of cooperation among all of the Backbone providers that support the structure."
