Ground Stop

[Busher]

Any weekend flights planned? The FAA just issued a nationwide ground stop. Inbound flights will land but departures are all stopped.

[Lazerr]

It's already lifted I thought?

The FAA says it is not a cyber attack. It's not lifted yet as far as I can tell. Unless they know the exact cause and how the problem happened they cannot exclude the possibility of a clever cyber attack. IMO.

Too much overtime?

[icepac]

Somebody is probing.

[AKKuya]

Aliens again?

[Busher]

Aliens again?

Maybe but more likely... 50 year old technology.

Two paper cups and string never fails.

[Eagler]

We won't know the truth..

And it will soon be forgotten when the next strange experience takes it place..

I’l bet it was the newer and internet connected technology that stopped working.   

[AKIron]

There are valid reasons for both Microsoft and the FAA to hide the real reasons for the failures. Whether enemy nation hackers/AI were involved or not it's foolish to believe we are safe from such attacks.

[AKIron]

It's getting harder to believe this is coincidence.

Switching from copper wire to fiber would not cause that, except for the actual “switcher” unit time to click over, once connected. Milliseconds.

However in fiber, addresses in the “universe” unit must be assigned prior to going live

That said, digital is great when it works, sometimes it can be a head scratcher getting there.

I’ll bet it was up in less than an hour. The rest of time was decisions to stop grounding.

Maybe they used a TP-Link router that had a back door in it.

Seems to be some contention over the claims of antiquated systems. A contractor says modernization is 70% complete. I would argue there's nothing inherently wrong with networks over copper.

"L3Harris, the federal contractor at the center of Friday's nationwide FAA ground stop, said Saturday it is assisting federal investigators as officials work to determine what triggered the massive disruption to American air travel Friday.

The company's statement comes after Transportation Secretary Sean Duffy identified L3Harris as the contractor performing routine maintenance when telecommunications failures began cascading across the nation's air traffic control network.

L3Harris defended its ongoing efforts to modernize the nation's aging aviation infrastructure, saying it has completed more than 70% of the planned conversion from legacy copper wires to fiber optics alongside its telecommunications partners and the FAA.

"We are supporting the FAA in its investigation to understand the conditions that led to the Nov. 13 ground stop of our nation’s air travel," the company said."
