What about ground to satellite communication?

That would be radio links. Not many satellites connected to the ground by copper cable.

  • Yeah, I was asking generally with regard to panic involving "computers and everyday electrical devices", which I thought would be obvious, apologies.

honestly I'd be more worried about the upper atmosphere puffing up and taking out low satellites, like what happened with a starlink launch last year.
