"Frequency outage", I think that translates to radio communications not working, until "22 Zulu" aka 22:00 UTC, 5 PM ET.

How does one prevent transmission on a frequency in an area the size of the continental US?

It's radio. Either you jam it or it works. That's the selling point.

It's not the transmitting per-se. The network that gives controllers access to the en route radio system isn't letting them connect to the radios.

I can easily imagine a batch job on a mainframe that sends every hour some important data by mail and that some logic apps checks that mailbox to propagate the data but now that mails have been delayed +12hours it's going haywire

I disagree vehemently that programmers build lousy programs. Many of us do quite the contrary.

But this is hilarious, and hence I am upvoting.

What are all the possible reasons to do this?

Has this ever happened?

A credible threat from Iran? More likely a technical issue.

Happened in 2023 https://www.faa.gov/newsroom/faa-notam-statement

It happened on 9/11, didn’t it?

And in 2023, which was more similar to this. This is a departure stop, planes in the air are still heading towards their destinations. This is not the same as 9/11 where flights were redirected to their nearest airports for immediate landings.

Why? I came into this thread just to make sure someone posted that link. I hate when the discussion gets fragmented across several different posts.

More likely: the reengineered system has a serious bug.

This has been a horrible week for AI: Jensen resigned, Microsoft Outage, now FAA outage from new AI system.

The reason is clear: all this points to the ANT ipo next week, people want to pop the AI bubble.

1. There’s no proof yet that this is AI related

2. The idea that someone would ground all air traffic in order to disrupt Anthropic’s IPO is an absolutely wild conspiracy theory with no basis in reality

What a cope. Per occam's razor, the most likely cause is putting hallucinations on the critical path. But sure, peddle a conspiracy theory.
