What will happen when someone detonates a large nuke in earth, next to data centers?

A lot of people will die, and the attacked country, or its allies, will shoot nukes back.

A nuke in space would not kill anyone, but the proximate result might be serious economic damage.

Inverse square law. Plus, I think a lot of data may be stoted and processed out at the Lagrange Points.
