From yesterday:
post
ADSB (live map of all air traffic) over the US is pretty damn interesting right now.
Afaik atm, anything leaving from the US, headed to somewhere in the US, is... indefinitely (?) grounded.
Outbound to international destination flights do appear to be leaving from some airports, flights crossing over the US from say Mexico to Canada are still en route... oddly I think I'm seeing flights that are ultimately international dest outbound... but have stopovers at US airports... are still ... going to US airports?
I genuienly think this is 'we turned on our new vibe coded slopgorithm that "optimizes" internal US flights' ... and it immediately shit the bed.
Also from various live coverage I'm seeing, many many reports of passengers just being in a grounded aircraft, on the tarmac, for 2 3 4 hours, then apparentltly the airlines just eventually give up and deboard them.
Yeah I've been watching the LAX livestream and they've been keeping those airstairs moving. I have no idea where they're going to put all these planes, the poor ATC controllers.

... this makes me less annoyed when some idiot triggers an impromptu fire drill at my apartment.
Sure, that's annoying.
This?
LOL guys wouldn't it be funny if we just, pulled the fire alarm at every airport in the country, at the same time, and were also in charge of the fire alarm system, and also just like, didn't say anything specific or meaningful regarding what was going on?
... is it possible for the FAA or people in it to be found to be, like, criminally materially negligent?
Perhaps they weren't quite ready to stop using floppies.
The outage appears to be affecting a telecommunications network overseen by L3Harris Technologies, according to people briefed on the matter. The network handles crucial radio frequencies that air-traffic controllers use to communicate with pilots, the people said.

wth, why is everything happening at once??
Listening to the JFK ATC live feed and it's crazy busy. I feel sorry for ATC there.
Edit: you can watch a replay of the ground stop here.
As of 6:14pm central, I'm seeing planes taking off on the flight radar. Specifically a plane registered in the UK leaving Chicago, 2 leaving Seattle, 1 leaving San Francisco.
Perhaps they're letting a few through?
The issue is the routing within the US. If a flight can take off and immediately leave US airspace (ie. east/west coast or near the Canadian/Mexican borders), they can go. For example, I just found one taking off from Detroit and flying over eastern Canada to Amsterdam.
Update from the livestream (sorry, bad source) and their claim is that they overwhelmed the networking.
So the theory that they did absolutely no testing or integration with the legacy network/systems they plugged their dipshit AI system into seems to be 100% spot on.
Update: "old wires. We have old copper wires, we need them upgraded" hey sysops wonks, have you checked the expiration date on your ethernet??
More update: Okay so their explanation is that the legacy network got overloaded with traffic and cascaded. Coincidentally, they turned on a massive new AI system yesterday that relies on this network.
The head of the FAA claim on and claimed that Trump has been calling for an upgrade for more than a year. Sounding more like a really lame false flag.
I laughed out loud when the reporter asked "then why hasn't this happened in the last two years, since republicans controlled and still control both the house and senate?"
Honestly, there's just no point to this being a false flag - aside from that they've gone up and down assuring us it wasn't a cyberattack and never even mentioning Iran. Honestly, from the press conference this sounds exactly like Duffy (apparently his real name) and cronies dumped a fuckton of traffic on a system that runs on equipment from the 80s (because it's reliable within it's context) and they didn't do any testing with the extant isolated network so the whole thing cascaded.
That seems like the most likely scenario; fucking idiots got put in charge of a critical system, decided they could improve things by taping AI to it, and subsequently broke the entire country's ATC network because they're, again, fucking idiots.
