Interesting.
The arguments I’ve heard from a few data center builders/managers is that the
main factor in how a DC is built is that can the business be insured against
catastrophic loss. It has to meet all fire codes and has to be reasonably
resistant to unforeseen catastrophes, like flooding

The NCAR Wyoming Supercomputer Center has raised floors of about 20 feet. The
auxilary cooling and PDUs are installed down there. Needless to say, you don't
pull a floor tile there unless you are on the facility staff!

Not at all. They were 2 foot squares sitting on adjustable

If you mean "when properly installed", pretty well.
If you mean "as actually used", not at all.
With the exception of the very small raised floor under
the HP-3000 in my high school, every place I've encountered
raised floors there

M or 2 in the elevator takes you to the overhead ca ble area."

The logo is sort of wrong for the era. I think it is just a sticker

And I do not think Puma would have been running on just a model 20,

I do not think this is correct. The IRIG almost certainly refers to the Apollo

one of the PSA trays Adrian’s contraption is supposed to be testing:
