I don't think this really works out. Putting a data center in orbit is basically a question of moving lots of mass which is always going to have a large energy cost for accelerating all that mass. On the other hand someone wanting to damage that data center only has to get the mass of one decently sized bomb to the same velocity.
Unless you're talking about an adversary who has ~no launch capability then the person trying to put the data center out of reach is always going to be massively disadvantaged in terms of the physics.
