Its kinda interesting reading the story of the Oct '73 cable cut or seeing the old route maps for the L-1 cable and the microwave reroute. Excavators dug up copper cable in the old days, long before they developed their well known taste for optical fiber.
Its secret in the sense of you probably have no idea of the location or routing of the wires between you and the nearest central office, but if you looked up at the phone poles you'd rapidly get the idea. Not secret in the sense of the world being run by a cabal of reptilian space aliens.
I found multiple references the bunker onsite got sold (probably for warehousing) but google maps hasn't been updated. The maps aerial view shows it covered in semi trailers.
How did you find out about that!@?!?? Who have you been talking to? Don't move, some very nice people are coming to cough talk cough to you tonight!

This is a facility of some sort which is apparently owned by AT&T, was supposedly abandoned years ago, but which started seeing some new activity a while back. The thing is an underground bunker of some sort... zoom in close and you can see how the road leads underground. There are all sorts of local crazy rumors and shit about what's actually there, if anything, and what goes on / went on there.
So far as I can tell, the closest thing anybody has gotten to an "official" story on the site is that it was formerly part of the military AUTOVON phone network.

I don't see very economic re-purposing possibilities even today when more are within fiber rollouts. With their current price points, no business plan built around one of these I've tried has ever penciled out sustainably. Has anyone else tried to run the numbers and come up similar results (you don't have to share the plan, just that some business purpose pencils out)? I don't see a lot of businesses buying them, and I'm guessing the majority of purchasers of these sites are private individuals with either deep pockets or a mania for industrial-grade and -scale home improvement.
IIRC, I think the tower I'm thinking of points to the northeast. It'd be pretty cool so figure out the links that used to be connected!
