Personal anecdote:
A relative of mine has his own business that covers all sorts of IT stuff.
He has a starlink running permanently as a backup because a couple of times a year his fiber experiences some downtime.
I run two independent (Technology + Provider wise) internet links for our house, as both my SO and myself are permanently working from home.
I would be massively irritated if the White House would not have multiple levels of redundancy. Which makes the article just more confusing.
