It should be fine to update at any moment. Why? Because systems like this ought to be hot spare or blue/green models that have a full working copy at any given time, and a failover/failback.

A reasonable deployment plan considers the reality that the deployment could fail. One mitigation is to choose ideal conditions for a possible failure. You’re correctly pointing out one of the mitigations, but it doesn’t render the others unnecessary.

You can also have reasonable updates done at reasonable times that don’t show issues until unreasonable hours - or something else fails.

But what I’m hearing is that one company “L3Harris” could take down the airfristructure anytime it wanted to. That’s not great.

As opposed to what alternative? Being run by the FAA itself or with contractors? Being run by the DOT?

Well, it worked so far, I think it is great. 100% availability is a dream.

That’s why for example, you have ATC Zero protocols when communications go out all of a sudden at airports. And I imagine there is something similar for airborne planes that are not near any of their destinations.

		Yeah either the FAA or the DOT sounds good. Not contractors tho.

I mean sure and we have that in finance but there’s no amount of time saved that could make me deploy something during market hours

		Airspace certainly has busy and quiet(er) periods, but the skies are open all day every day.

Sure, but if it fails and a fallback takes over, will you be going home and having a nice weekend? Or will you be stuck at work over the weekend to fix it?

Well clearly they don't have a hot spare or blue/green models, or working failover.

		Which is why deploying at 3pm on a Friday is even more bizarre.
