This is because those specialized spaces to support computer infrastructure were built during the 1960s—a time of civil unrest in the USA, particularly on college campuses. It was felt that the large mainframe computers of the day would be targets of anti-corporate sabotage. Basement bunkers were more defensible and generally didn’t have handy windows for tossing firebombs through.

This is a post about AI data centers.

We used large amounts of basement space in Holmdel, but we were a big mainframe center for the Labs.

Note for all you younger folks out there, Bell Labs Holmdel was abandoned for years and then repurposed. The building you see in the “Severance” exteriors and some of the interior shots is the old Bell Labs Holmdel building. It was also the location of my first Sys Admin job after I graduated in the late 1980s.

They had computer rooms on the second and fourth floors.)

INTELLIGENCE
CENTRAL ARTIFICIAL
<--------- --------->

The CIA office was using a cover name there; it wasn't supposed to be public even though everyone knew. IBM and Polaroid were other tenants into the 1980s who had left before I arrived.)

As computers shrank, more and more of the computing was distributed around the building, and the ninth floor was slowly converted into lab and office space over time. Because it was a spec office building, the other tenants had computer rooms on their floors, which we gradually took over.

That building is now Moderna HQ and probably doesn't have any computer rooms any more.

See, e.g., https://www.columbia.edu/cu/computinghistory/#year1960 — the Columbia University Computer Center (where I spent far too much time as an undergrad) was located underground starting in 1963, well before campus unrest. The Berkeley Free Speech Movement, one of the first large campus protests, was 1964-1965 (https://en.wikipedia.org/wiki/Free_Speech_Movement). I think that many academic computer centers were in basements because that's where there was enough space available.

I know it's under a massive office complex where a lot of costs are shared. I actually know of another smaller data center in a similar office complex and I know the cooling costs are shared between tenants(from an old deal with the owner of the building). I want to say that is sorta how it's working with the vault one too. For the vault data center there are two massive generators way on top of the many floor complex and it's run allll the way down into the basement.

I wonder how they managed it?

Not built in the 60s though. Well, the vault probably was but was repurposed into a data center in the early 2000s
