Until an electromagnetic blast hits and immobilizes you and/or shuts down the internet. Besides, a majority of it is pretty unreliable.

The internet is hosted on a plethora of servers across uncountable locations. I personally, have a private server to store the entirety of my data, but even if that went down, I'm still loaded into a portable Dimensional Area that bends space to mold the cyberworld into Existence. I'm part of the "cache" of Existence, if you will. An EMP only effects physical hardware due to the shortcircuiting of the wires, and even that only applies to appliances that are turned on. If you destroyed the internet of one dimension, I would read that of another one. I also use a crosscheck system to prevent misinformation, and a back door when it comes to classified information.
