"there were no humans on board"
Made me think of this:
"The factory of the future will have only two employees, a man and a dog. The man will be there to feed the dog. The dog will be there to keep the man from touching the equipment."
I assume the same dynamic is at play, but I find the entire thing to be riddled with hubris, and projective of industry for industry sake.
The first thing I thought of when reading this article is whether the increased shielding from the water reduced the impact of cosmic rays on the hardware.

It's also a really good random number generator, for those Hackers/crypto people that would like a true source of randomness.
I think (but have no reference) that the amount of cosmic rays the planet blocks by being in the way is dwarfed by the effects of the magnetosphere and solar rays.
Back when I worked at a supercomputing center, we had "operators" on duty, who were supposed to visit the machine room every 2-3h or so and check several things.
It turned out that they were the major cause of hangs and reboots of our SunSITE server (a large FTP archive) — walking on the lifted datacenter floor caused vibrations which were enough to disturb the (terrible) external SCSI connectors to multiple drive arrays.
So, I can certainly believe that statement.
Maybe securing the vertical bars after the entire thing slides horizontally into the tube?
I'm assuming the tube has some rails they use to slide the racks in but then they have to be properly secured in place.
Needless to say whenever I was there I kept having flashbacks to the first Resident Evil movie.
That does sound plausible. But I do wonder how much might have been due to extra care. If I were the sysadmin on the project, I probably would have spent extra time on component selection, cable seating, burn-in testing, etc. Lots of pressure for it to do well.
Edit: Unrelated, but this picture is funny to me. I don't think there's enough room to slide that server out, so I'm not sure what he's doing. https://ichef.bbci.co.uk/news/800/cpsprodpb/48D6/production/...
