"Satellites offline".

Well, actually they do NOT turn satellites "off" or "offline" with Starlink.

Those satellites are indeed online, and "on", but just simply drop data packets that come from behind the Russian geofence, and ignore them.

Essentially each little Starlink satellite serves a huge array of other countries all around the world, during it's 16,000 mph orbital speed! So it doesn't "hover" just above one area. Instead each satellite circles the entire Earth once every 90 minutes.

So it has to remain "on" and functional for when it passes over other service areas.

The reason this new type of fast flyby satellite system can work is because there are simply so many of them. So when one of them moves out of range (falling over the Eastern horizon), another is coming into range (rising from the Western horizon), and another, and another...
