All European and Mexican departures to the US have been stopped: https://x.com/sentdefender/status/2121381457683964308

Update, 3:00 P.M.: Pacific bound flights are cleared to depart, including Hawaii and Asia.
reply
Makes sense. CNN reported that international airlines were still departing for North Atlantic flights, apparently because they use a separate communications system.
reply
Yeah, oceanic flights largely use satellite-based CPDLC today, or HF voice as a fallback, but not VOR in any case (which I suspect is the implicated system here).
reply
VHF Omnirange (VOR)[1] is unlikely to be involved. VOR stations are not dependent on a network. All they need is power. It's 1950s technology. The big ring of antennas next to US 101 just north of SJC is a VOR.

I'm stuck at SFO and a flight for Hawaii just boarded perhaps 20 minutes ago. I don't think it has taken off yet though.

two flights to tpe and a flight to tokyo took off since 3

Surprised there's not been any updates yet. Not even one of this will continue or it is being resolved.
reply
Sec of Homeland Security gave an interview about 10 minutes ago saying it's indefinite, they don't know the cause, and to expect resolution to take a while.
reply
Oh wow. That's not really good, is it.

Economy taking a lot of crazy hits this week. They're footgun hits too, not even enemy action.

Edit: ok so one of them was maybe a little bit enemy action.

reply
I'd say that's not really known yet, although there's certainly a footgun element at least.
reply
I'm sure Jensen had some enemy action.

There’s only so long the American wall of competence can be chipped at by stupid, before bigger chunks start dropping. Watch out below.

When will we congratulate all the AI companies for this?

Probably someone prompted an agent: solve global CO2 emissions :-)

SFO had delays this morning because of winds. I'm not sure if LA also had bad weather, but SFO had a lot of rain and if you know SFO, you'll encounter a delay if someone sneezes in the direction of the runways.
reply
I actually got out surprisingly on time at 10:30am. The other airport at landing was chaos though.
reply
Info on this is amazingly sparse. Apparently Sec. Duffy posted something on X/Twitter, and that's all the news media have

Maybe look further than Twitter.

The legitimate media from the New York Times to CNN and beyond all showed video of Markwayne Mullin's news conference 20 minutes before your post.

I'd be quicker to assume that the problem is within. AI related or not.

You need to go outside, take a walk and then have a hot chocolate.

All is well, this is not the AIpocalypse. Just some dude fucking up something stupid, as usual.

Update before I can no longer edit:

> The Federal Aviation Administration told airlines the nationwide outages that prompted the ground stop were the result of a problem with network routers, according to an airline source.

> The problem is believed to have started at Chicago Midway International Airport and cascaded nationwide.

> A spokeswoman for the military’s Northern Command and the North American Aerospace Defense Command, or NORAD, said there was no evidence yet that the telecommunication outage was the result of any nefarious action by domestic or foreign actors.

What possible basis could you have for saying this?
reply
A decade of experience solving nationwide problems because someone somewhere did something stupid, before I retired.
reply
This is a pretty reductive response given the circumstances.

If you prefer a more lengthy answer.

If there was an attack on your country, my phone wouldn’t stop ringing, just like it did 9/11.

All I am getting is pictures of baked cookies right now. So there is no attack on your country.

Planes are not falling out of the sky, as you can see on publicly available platforms. Nothing is exploding on the ground, besides the poor souls choosing Taco Bell for dinner.

I am confident you will not be abducted or murdered by Aliens today either, pinky promise.

So whatever happens is not an immediate danger to the planes still in the air. And no danger to anyone on the ground.

The most simple explanation is that the communication between ground and air is not working properly, and as this is necessary to safely fly thousands of planes simultaneously, they should rather stay on the ground for safety reasons until they figure out what is wrong.

If you have any specific concerns not addressed above, feel free to share them.
