Thanks for the link. I clicked it and was greeted with this. LOL!

"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.

NordSteve |root |parent [-]

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.

Microsoft outage related??

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

If you refresh a few times it'll show the advisories.

Looks like the woodpecker has arrived.

elendilm |root |parent [-]

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

NooneAtAll5 |root |parent |next |previous [-]

previous time it happened right before chinese baloon made the news

it may be something similar - remove all random, but controllable sources of radar return for military to start scanning

It happened on 9/11, didn’t it?

stmw |root |parent [-]

yes, 9/11

Jtsummers |root |parent [-]

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.

+1 ban it and with it the 30k+ Karma it has

cactusplant7374 |root |parent |previous [-]

Dang does that too. I guess we are going to have to ban him as well.

I guess some of their floppy drives must have given out.

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.

afavour |root |parent |next [-]

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

mcdonje |root |parent |previous [-]

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