So for the things that don't need a lot of change, what are some characteristics of the system?
Does CI/CD exist? Does CI even exist? Are deployments automated? Is data sanity checked before loading? Is there a development environment? Do things like hourly snapshots exist? Can you easily provision a replacement system from scratch and restore data from a known good snapshot?
Or, is every process manual, slow, and error prone because there's never been a need to move fast.
Look at this one sentence in the article:
> In the overnight hours of Tuesday into Wednesday, FAA officials decided to shut down and reboot the main NOTAM system -- a significant decision, because the reboot can take about 90 minutes, according to the source.
So they do a reboot, that takes 90 minutes for some reason, and then that didn't even fix the problem. Their system that needs a lot of stability is now broken.
