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.

If Amtraks were more luxurious, I might agree with you, but these days you might as well be riding Snowpiercer (and I don’t mean the good parts).

In that the wealthier clientele have better accomodations? Outside of Southwest isn't that true of airplanes?

But I'd like to see more investment in rail & a better coach experience, absolutely.

I read it as filesystem corruption from a bad disk, coupled with redundancy that doesn't actually work.

I find it quite weird multiple things failed on the same day, such as the UK post office system unable to deliver abroad

I suspect this is just statistics, like "it is likely that two people will have the same birthday in a roomful of people"

What kind of database are they using, I wonder, to end up with such a spectacular failure?

Cosmic rays are a cop out but a good plot device. They're so rare, but one could write a bit flip into a script for a novel or a tv show as the solution to any computer mystery.

Aliens using cosmic ray generators to flip specific bits and set off nukes.

Reminds me of the Sophons in The Three-Body Problem

I wonder if the corruption could have been caused by a cosmic ray bit flip. It would be funny to think that one single tiny subatomic particle knocked down our entire flight system.

One more reason to use ZFS.

Maybe Bobby Tables is getting into the NOTAM system now
