Again insists the Ai install wasn't the issue and then explains contractors were replacing old copper lines with fiber and either did a poor install job or installed a faulty router. That led to traffic overwhelming the system and then it travels one node to another overloading them.
So then someone asked him if what Mullin said last night was true or not and he then tried to explain that while yes the new Ai system greatly increased network traffic that wasn't why it happened.
We're watching a guy on CBS right now who says Duffy is lying through his teeth. The Ai system advises them on how to reroute planes to cut time off the routes, on average about 10 minutes, one route they cut about 50 minutes by going around weather systems and other things. But that information is additional network traffic and it's for literally every flight. So the reason it happened yesterday is of course Friday is a big travel day it was the biggest travel day since the upgrade and now they found out all that additional network traffic overwhelmed it. He said even if you accept the claim they replaced copper with fiber and there's a failure the system is supposed to just reroute traffic around the faulty router but if the system is overloaded that doesn't solve it
It is 100% true the system is old and needs to be updated but this is why experts were telling them they were going too fast. 25 members of Congress signed a letter 6 weeks ago telling them if they didn't slow down something like this would happen
