Thanks for the link. 
I clicked it and was greeted with this. LOL!&quot;It seems the shiny new AI tech tool Strategic Management of Airspace Routing Trajectories (SMART) may have become Failed Airspace Routing Trajectories (FART)&quot;

It&#x27;s not the transmitting per-se. The network that gives controllers access to the en route radio system isn&#x27;t letting them connect to the radios.

How does one prevent transmission on a frequency in an area the size of the continental US?It&#x27;s radio. Either you jam it or it works. That&#x27;s the selling point.

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

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&#x27;s going haywire

previous time it happened right before chinese baloon made the newsit may be something similar - remove all random, but controllable sources of radar return for military to start scanning

It happened on 9&#x2F;11, didn’t it?

What are all the possible reasons to do this?Has this ever happened?

I disagree vehemently that programmers build lousy programs. Many of us do quite the contrary.But this is hilarious, and hence I am upvoting.

If you refresh a few times it&#x27;ll show the advisories.

&gt; I guess some of their floppy drives must have given out.More likely: the reengineered system has a serious bug.

1. There’s no proof yet that this is AI related2. 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&#x27;s razor, the most likely cause is putting hallucinations on the critical path. But sure, peddle a conspiracy theory.

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.

All US airports are currently ground stopped
