The Outer Space Treaty is very very clear: anything launched into space is the responsibility of the country that launched it. Even if a private company payts for it and operates it, it's still the responsibility of the launching nation. Even if you launch from international waters, your operating company is still registered to a specific country, and the company is made up of citizens of one or more countries, and it is those countries which are responsible for the satellites. Those countries, in fact, have the responsibility to make sure that their citizens follow their laws and regulations. Unless you and your entire team are self-sustaining on that datacenter in outer space (maybe possible a century from now? Maybe not possible ever), you will be hunted down by the proper authorities and held to account for your actions. There is no magic "space is beyond the law" rules; it is just as illegal- and you are just as vulnerable to being arrested- for work done on a datacenter in space as work done on a datacenter on the ground.
