A single malfunctioning FAA router in rural Arkansas appears to have caused the air travel chaos that grounded all flights across the US Friday, according to a new report.
The problem originated at an FAA radio site in El Dorado, Arkansas, where a newly installed router flooded the network with excessive data traffic, disrupting communications between pilots and air traffic controllers, the Wall Street Journal reported.
“We saw two places that were actually pinging our network at a very high rate, a thousand connections over every four to five seconds,” Rebecca Guy, the FAA’s technology chief, said on Saturday.
The outage affected 17 of the FAA’s 22 high-altitude control centers, forcing officials to issue a nationwide ground stop.
More than 3,500 flights were grounded during the roughly five-hour shutdown.
Officials are investigating whether defective equipment or installation errors by contractor L3Harris caused the failure.
Another router in Amarillo, in the Texas panhandle, is also being eyed as contributing to the outage.
The FAA states that there was no evidence of a cyber attack.

I’m not buying that answer. I have been familiar with large nationwide systems, and there is always redundancy on every level. One router would never kludge an entire network like that. Someone made that call.
Sure, Jan.
Yeah, right.
At the same time, if we recognize that the average govt operation is no better than the average New Jersey DMV, this is entirely plausible.
Trust the science, safe and effective, a bat in a wet market, they hate us for our freedoms, Biden got 81 million votes, Ukraine is our ally, Israel first, diversity is our strength, a router in the middle of nowhere,...... the list goes on We are drowning in bullsh*t
With 20 years of experience programming Cisco System routers in large nationwide or one case worldwide computer network, a single router in my experience has never brought down the entire network.
We are talking about the Federal Government but it’s hard to believe even they could design a network that easy to bring down.
One of the pilots said the entire episode was horse caca.
Sounds like cyber attack to me. New router and exploited zero day vulnerability.
“One router would never kludge an entire network like that.”
Sure it could.
A bridging loop due to no Spanning Tree configuration..
Or, if they are advanced enough (I hear they are NOT) it could be an OSPF Area/Cost conflict.
The real question is why it went on for 4 hours.
I’m starting to think that our government lies to us ...
“a single router in my experience has never brought down the entire network.”
Thanks for your input on this.
It does seem hard to believe.
It wasn’t Mena?
A single malfunctioning FAA router ....
... in El Dorado, Ark...
What is this supposed to be, comedy gold?
See post 10.
This can easily happen. All it takes is a typo in a BGP config entry and the entire network will collapse immediately once the erroneous entry propagates (it happens immediately when it comes online). What is not explainable is why it took them 4 hours to figure it out.
that’s what I’m thinking. BGP or OSPF config error. but if you are the field guy who brings that online and everything immediately craters, you get the feeling of all the blood running out of your head and you know what happened within 60 seconds. why was it down half the day is my question. i guess it could have been an edge device owned and controlled by the carrier, but still...
