It wasn't even in full production, and I am not aware of much equipment
that solely relies on Galileo.

A lot of devices today can use multiple GNSS and this is great, as this
incident shows that one of them can go offline. Relying on only one of
them is risky.

This outage and its lack of ramifications doesn't imply that if GPS went
offline there woulnd't be consequences. Galileo is just a few years old,
and wasn't even in production. If GPS would go offline, you'd see a lot
different fallout. Lots of things rely on GPS solely.

Worthwhile noting however that they’re not reliably pushing notifications to people on their notifications list.

Worthwhile checking fundamentals you do depend on with your own low level monitoring.

I suspect the Vatican was involved :)
