Air traffic in the USA has suddenly been grounded. The cause is unclear, possibly related to the Microsoft outage.
Could this be sabotage?
Are we living in a new cold cyber war?

Or maybe it’s Biden’s fault?

Hopefully nothing major.

Reportedly “a communication issue impacting all Air Route Traffic Control Centers.”

No indication of an attack - homeland security secretary​

US Homeland Security Secretary Markwayne Mullin is speaking to reporters at the White House now.

He says there is no indication this was an attack against the United States.

"This is a telecommunications outage," he says.

"All the flights are accounted for," he says.

US Homeland Security Secretary Markwayne Mullin Quoted as saying “ this isn’t another 9/11”
BBC is quoting him as saying a “telecommunications outage" has led to the ground stoppage.
Cyber attack ?

Have you tried turning it off and on

Nah, they communicated via email

It’s going to make the recent UK ATC meltdown look like a small blip (it wasn’t!)…

Hopefully nothing major.

This is relatively major, only 2nd time this has been issued since 9/11. The longer they're offline (every extra minute) the bigger the snowball gets.

Sounds like many (most?) atc centres have almost 0 communication capabilities to planes.

Another form of misery map, all the arrivals that now dont have a gate (LAX):



This United flight has been sitting there for 2 hours....

FR24 shows international flights from west coast still departing . And I presume any OCTA (or VFR in CTA?) are good to go ( but that precludes almostall RPT).

 

[scaredeycat]

So how is all the traffic currently in the air supposed to cope? Surely there are areas where weather is problematic. Is everyone just flying by visual rules?

Looks like some east coast have departed too heading over the Atlantic.

According to another site pilots are communicating between themselves to try and keep separation….scary thought
