Every chance I've had to interact with satellite operators in conferences, I've asked them about their plans for dealing with solar storms (I'm particularly worried about Starlink, which requires dozens of maneuvers per day to avoid collisions. What if a large fraction shuts down for a few hours?!)

The universal response to my inquiries has been "Don't worry about that, it'll be fine!"

I guess we're going to find out very soon. swpc.noaa.gov/
