Thanks for posting this, Dallas59. It’s a fun video.
Not sure I like to see the major hub street addresses made public.
This is what the people at the internets want you to believe. Do you think it is just a coincidence that there are 7 layers.

Lots of erroneous engineering info.
“Large underground copper wires.”
Truth: large BUNDLES of small copper wire pairs (in some obsolete locations) - IIRC, One strand of single-mode optical fiber will carry 130,000 phone conversations, the equivalent of a 4” diameter cable with hundreds of small copper wire pairs.
“Fiber optic cable buried deep beneath the ocean” Nope. Unless it is crossing a harbor or near shore where dragging anchors are a problem, the cable carrying many optical fibers just lays on the ocean floor.
“riding a fiber of glass as thick as a silver dollar” The outside of one optical fiber is 125 microns in diameter. Cladding brings that up to 250 microns. The actual core that carries the light in single-mode fiber is about 8.3 microns. A micron is one millionth of a meter or one 1,000th of a millimeter. An average human hair is about 100 microns in diameter.
The complete CABLE with many optical fibers, protection layers, tensile strength members, etc is the diameter of a silver dollar (or larger in some cases).
