There are also a lot of Telcos building these sorts of buildings. Actually, having seen a video on this exact house[1], I'm pretty sure I've seen it before, too. "Built in the 90s by at+t" says the video.
lol “shadow operation” what? This house was built before cryptocurrency was even a thing. It’s an old AT&T switching hub that was disguised as a house so as to not make it an eyesore in the middle of a neighborhood.
There may have been a national security aspect to making it look like a normal house, bunkers have been disguised in a similar way [1] elsewhere.
