Based on ocean coverage there's a 0.7 probability that it'll just make a big splash.
Should we ever get to a point where a country is considering shooting down space datacentres, considerations about the impact on Earth is unlikely to stop them.
>will probably break up
if it is designed to breakup. And not if it isn't.
>no nuclear material involved
that is the beauty. No contamination.
>that's not going to have a huge impact.
in my comment i already specified the TNT equivalent of such an impact.
>there's a 0.7 probability
It isn't a matter of probability. You can deorbit with high precision, and pretty much hit any desired target on the ground if you have thousands of objects in space on a bunch of various orbits.

13 ton GBU-57 reaching M 2-3 gets 200 feet deep. De-orbitted 1-2 ton steel rods will have about the same effect - ie. you can hit many strategic objects of your attacker. And having in orbit, just in case, a ball or rod of 30-50 tons will get you a small tactical nuke equivalent.
