## Key points

- Duffy says an Arkansas router may have triggered Friday’s ground stop.
- It allegedly made over 1,000 connection attempts every five seconds.
- Investigators are examining two routers as the fibre upgrade continues.

## Summary

Transportation Secretary Sean Duffy said a router installed in southern Arkansas may have caused the communication and data problems behind Friday’s nationwide ground stop. Investigators are examining the equipment, while Duffy said they remain open to other explanations.

The stop lasted more than four hours after unstable radar and communication feeds raised concerns about air traffic control connectivity. Duffy said the router generated over 1,000 connection attempts about every five seconds; it and another router are being examined at an L3Harris lab in Florida. The fault arose during a copper-to-fibre upgrade, which L3Harris says is more than 70% complete, and flight disruption continued at a lower level on Sunday.
