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"
A corrupt file led to the FAA ground stoppage – also found in backup system

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.
Are you aware that an Amtrak passenger train was stuck in South Carolina for 39 hours this month? Some of the passengers felt they were being held hostage. At least at an airport you can walk outside and catch an Uber.

#93I have a feeling the summarized age of the hard drives in that system exceeds the age of the United States itself (which is 247 years). When fsck was introduced in 4BSD in 1980, it checked every filesystem on boot because it had no better idea. If this thing is, say, forty years old then that's exactly the right age for this...

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…
Southwest?

Amtrak isn’t allowed to be successful
Either way rather be stuck on a train then a plane anyday

#96Quote from FAA: "Our preliminary work has traced the outage to a damaged database file." UK news source The Independent is reporting that Nav Canada's NOTAM system also suffered an issue.[1] Speculation: corrupting input, either international or North American? E.G. UTF-8, SQL escape, CSV quoting. edit: Better reporting of Canada's issue from Canada's CBC (and frankly, better reporting about the US, too). [2] "In Can…

What is your preference based on?
Probably he’s been to… any airport. Maybe they’re bearable if you can get into a lounge
On the train there's more room, you can move around, and the atmosphere is more relaxed.
Some people like planes. I saw an HN comment where someone said they took lots of "flights to nowhere" over COVID and used the plane as their office. I don't understand that at all. But to each their own.
I will say the views are unbeatable.

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

What's funny about this is that the FAA obviously knows what can go wrong with "yeah we have two of them" as they wrote ETOPS regulations to avoid some of the common pitfalls or amateur mistakes. They then failed to apply that to their software. Obviously at a big government agency, the same person is not writing both aviation regulations and software procurement contracts, but the institutional knowledge is there. N…
This seems to pose an interesting question that's out of my pay grade. The fundamental problem seems to be: you've replaced two distinct systems (one new and far more capable + 1980s-era one that always works but lacks [new feature x100]) with the same one running on 2x different machines. So the weak point is you ultimately share the same database/data structures/memory+logic flows between two systems. So if you kee…
