Gosh, you totally missed my poetic point. Thanks for your testy left brain correction.
How about…
The base, essential operational foundation of the Internet is located on the physical plane,
where it is subject to unforeseen physical threats such as fire, flood and/or interruption(s) of electrical power sources. In other words, the Internet operates according to (and against) often unpredictable physical TERRESTRIAL laws and is not merely some Mankind-formulated lofty “cyber illusion” beheld collectively by the majority of Earth inhabitants connected physically to the Internet and its various coded sub-sets.
Not as poetic, but perhaps slightly more satisfying to the more analytical among us.
