Interesting question ! Harsh radiation aside, I can think of several reasons, the first among them being that the old limiter C is still in place. Whether 1s and 0s or qbit, they will still have a 'lag time' when accessing resources. Our own moon as you're aware is a mere 2 light seconds away, but 2 seconds is an eternity to a machine based intelligence. I would speculate that the same reason it is built at all and inhabited by one (or more) 'uploaded' minds, is the reason for the location. Perhaps a natural resource such as a power source, wormhole, or other anomaly makes this an ideal location for this installation, and the 'uploaded' minds are there to provide virtual staffing, in an otherwise stiflingly remote environment. I can speculate that the enormous magnetic field around Jupiter could be harnessed as a virtually endless power source, and the station ( I think Ganymede would be ideal) It seems much thought has gone into this, I also suggest that an 'uploaded' mind is still a human construct, and would require a sense of corporeal stimulation of 'senses' to remain sane, particularly over long durations and remote venues.

I can speculate that the enormous magnetic field around Jupiter could be harnessed as a virtually endless power source. I think Ganymede would be ideal because Ganymede (7th moon of Jupiter) is in a place where the view is spectacular, but far enough away that it's not a threat to the moons' stability. Ganymede is also the largest moon in our system, and the only one that has its own magnetic field. Additionally, it has polar caps, a likelihood of subsurface water, and a very thin oxygen atmosphere. The temperature is a bonus for datacenter concepts.
I have worked on several datacenter construction projects, the first requirement is a safe location. If Earth has had EMP wars, this is the ideal place to keep the world's cyber intelligence, and if FTL communication is a reality, it is perfect for the ultimate ISP. It seems much thought has gone into this, I also suggest that an 'uploaded' mind is still a human construct, and would require a sense of corporeal stimulation of 'senses' to remain sane, particularly over long durations and remote venues.
