I can't read the article (I'd love a filter option to filter out paywalled submissions or YT BTW), but I would imagine Putin would love to take out a large number of skylink satellites. I wonder if any high atmospheric detonation would do this anyway.

  And if it does, and the US would see it as attack on her critical infrastructure, wouldn't it actually preclude high altitude detonations ? I assume that Putin would not like to poke the bear here, but I could be entirely wrong.

  > Putin would love to take out a large number of skylink satellites Sure, he want. But such step will lead to so huge consequences for low tech in all region (power grid, railroad signalling, copper networks), so will be considered inhuman action against all eastern Europe, and may be against Turkey region. This is definitely suicide action. It considered just because we know, Putin takes powerful drugs.

How can one protect their regular computers from this?

  It depends on distance from EMP device. For less than kilometer (mile), you need Faraday cage and all io devices inside it, and/or protected by NATO standard protection, and all these measures does not guarantee. For tens kilometers or more, electrically simplest surge filter will be enough, sure good to have UPS, but after first few seconds, this will only affect radio communications (more long wave, less UWB/microwave, like wifi), because extremely disturbances of ionosphere. To be exact, will be up to 20 hours strong low frequency waves (from hundreds Hz, up to tens MHz), they will affect power lines, railroad signaling (they are just few tens volts), copper networks, similar techs. As I know, ionosphere is transparent for 100+MHz, on which modern computers operate.

    Affect power lines, mean, their automatic safety measures will turn off power, and will need human intrusion to turn them back on. So, in case of powerful EM disturbances, power grid in region will not work few hours.
