What kind of database are they using, I wonder, to end up with such a spectacular failure?
Why would this be an indictment of any specific database technology? If your disk fails and corrupts the filesystem, you're toast, regardless of what database you are using.
I would not expect a disk failure to replicate to the backup.
AFAICT, this NOTAM system is a nationwide bulletin-board, using some cryptic standard abbreviations (to save space as if they were paying 1990s SMS), usually filtered by locale/coordinates/path, so pilots have the latest news hat might affect their flight plans. Has anyone seen exactly how many NOTAM messages are generated per day, and how long of a look-back is required? From 50k feet, it looks like something that c…
When I did my initial pilot training in the late 1980’s, the codes for METAR, TAF, and NOTAM had already long been in place. It was explained to me at the time that the encoding was a practice that dated back to its origins in the teletype era. I suppose the limited baud rate of these devices meant that economizing on symbol density was a good idea. I’d still much rather read these succinct formats because it’s easier to chunk it at a glance.

I will always elect to be stuck on an Amtrak than stuck on a plane or in an airport. I'll take a book to the observation car and read next to the Mennonites doing their knitting and love every minute of it, no worries from me.
What is stopping you from doing that in an airport?

Well, sometimes it's because you already boarded and started to taxi and there are so many planes on the ground that there are no gates open to get back to the terminal so you spend hours on the plane waiting for a slot to open so you can get off, meanwhile the galley runs out of food/drink and the toilets fill up. Then when you finally get into the terminal, it's chaos, no one knows when planes will be flying again…
On a positive note, you could have been on Amtrak: https://www.nytimes.com/2023/01/11/us/amtrak-delayed-va-fl.h...

This is highly informative. No seriously, it's probably the best thing I've read on NOTAMs. https://deathtonotams.com/ from there you can get to https://fixingnotams.org/ and pilots won't stop laughing and crying when they read https://fixingnotams.org/wp-content/uploads/2019/11/Field-Gu...
About 1.5 million per year.
