Not only upgrading hardware, but maintaining any issues along the way. Hard drives fail, Memory fails, etc. That’s just stuff that happens and can be easily remedied in a normal data center.

Now take all of those issues, and instead of being underwater… move it 500 miles into the vacuum of space. And take the heat dissipation of all that water, and make it a fraction because the vacuum of space is terrible at radiating heat despite the ambient temperature being so cold.
