Wow, I didn't know that this eventually knocked out a whole array of satellites! I wonder if there was restitution of some kind to the respective operators.

Edit: It seems the only disabled commercial satellite was Telstar [1], where it wasn't possible to point to a single cause because of Project K [2].
