Last time this happened, there were two effects: on one hand people making fun of not being able to upload their activities to Strava and on the other hand, and more seriously, people not being able to use their aviation navigation systems. Can someone comment if the Garmin aviation devices are affected?

Garmin glass cockpits don’t depend on Garmin services at all. Perhaps updating charts but that’s a monthly thing generally and it’s not done while airborne.

The “not FAA approved” isn’t a thing — there are devices that go in uncertified (experimental) aircraft, but those also don’t depend on live connections to Garmin services.

How would an aircraft be able to reliably “stream in” maps while in flight?

That argument makes no sense, other than a red herring saying “durr, glass cockpit bad”.

They don't. Glass avionics have a charts database that's physically updated about every month

Try visiting their FlyGarmin services at - https://fg.garmin.com - certainly looks to be down.

What indicates it’s down on that site?

It was loading a blank white page. Looks like it's back now though!

Likely they are, likely it "shouldn't" matter, as all their advertising says: "Not FAA approved [wink]"

...like, in an emergency it's cool to be able to click a button on your watch and see the closest airport, but you're supposed to have paper maps, a flight plan, a checklist, etc, etc.
