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

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.

> 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.

90 minutes; this certainly appears to be an advertisement about Windows OS.

I wonder what the cost of the reboot was to the FAA itself. Were a legion of contractors pulled out of bed to moniter the 90 minute reboot?

Quote 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 Canada, pilots were still able to read NOTAMs, but there was an outage that meant new notices couldn't be entered into the system, NAV Canada said on social media." "NAV Canada said it did not believe the outage was related to the one in the U.S., but it said it was investigating."
