FAA Advisory Page Shows No Ground Stop Despite HN Headline
FAA Issues National Ground Stop
The FAA's Air Traffic Control System Command Center advisory page, linked from a Hacker News post titled "FAA Issues National Ground Stop," displays only the message "NO Advisory." No ground stop, reason, or affected region appears in the source. The page is a standard ATCSCC advisory template with navigation links and no operational notice.

starting to see some explanations for what's going on

> 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. It wasn’t immediately clear whether the outage also affected the radar feeds that controllers use to keep aircraft safely separated in the skies.

> An update to the private communications network that connects America's air traffic control system caused the system to reboot, leading to a crash and a communications outage, multiple sources told CBS News. The system is operated by L3Harris, which did not immediately respond to CBS News' request for comment.

Info on this is amazingly sparse. Apparently Sec. Duffy posted something on X/Twitter, and that's all the news media have.
Looking at LAX departures, it looks like nothing has departed since about 10:30 AM PST, and everything later is showing Delayed or Cancelled. There are times after Delayed, but it's not clear those times mean anything. Some are now in the past.
"flysfo.com" is too overloaded to display departures. Stuck at "loading...".
JFK departure status shows almost solid "Delayed".
No good explanations anywhere.

Botched rollout of AI for ATC announced yesterday as rolling out nationwide?
> The agency wrote on Nov. 10 that after the D.C. test, it will “now use SMART in the airspace of all 22 centers across the country to reduce delays, reduce fuel consumption and improve the travel experience for the flying public.” The tech was already being deployed at some airports.

Secretary Mullin/DHS is confirming that this will likely be an extended outage...
> “This isn’t going to just be be resolved and turned around within the hour"

I have no idea whether this particular failure was Microsoft's fault, but I was in the air on September 14, 2004 when a substantial portion of the southwestern US's air traffic control went down:
https://spectrum.ieee.org/lost-radio-contact-leaves-pilots-o...
(I was near ORD at the time, flying toward the outage area. We diverted to ORD, and the pilot was very friendly about it.)
At the time I thought it was Microsoft's fault, as Windows 95 and 98 were susceptible to crashing when GetTickCount() overflowed, and this ATC crash was due to a 32-bit millisecond counter on a Windows machine overflowing, but in this particular instance the system was apparently not running on a version of Windows with this particular bug and the failure was just an application error.
Aren't computers great? :)

I'm watching it live on ADSBexhange, here's a flight I picked at random going approximately past me that'll land in Detroit about an hour from now... there's not much left over the US over 40,000 feet. Only 2 planes over Indiana at that altitude right now.

It's Delta Airlines flight 1070

Edit: It landed safely. Continuing to watch our airspace clear out, most traffic at 40,000+ feet is inbound international flights

Anyone have a screen shot? I just see "NO Advisory"

More info on AP [1]. Looks like a comms issue. The figures they quoted for the overhaul are absolutely insane - almost $45 billion (I used to work in telecom):
> "The government has been working to overhaul the outdated technology that air traffic controllers rely on since Congress approved $12.5 billion for the project last year."
> "Duffy has said that another $30 billion will be needed to complete the work, and the White House has begun lobbying Congress to approve it."

On a plane about to take off and obviously we didn’t. The captain is very confused and says he doesn’t know what this means.
