What to Know: Friday’s Nationwide Ground Stop Followed Equipment Failure
Equipment failures prompt halt
Duffy said radar and other communications began faltering at 3:36 p.m. He said the failures were not universal, but were widespread enough to lead officials to halt takeoffs nationwide.
Officials differ on cause
At a White House news conference Friday night, Duffy attributed the problem to old routers that had become overloaded. He said the failure stemmed from the system’s aging communications equipment, rather than recent upgrades.
Sen. Mullin said there was no evidence of a cyberattack. He suggested that new equipment and technology added to the old infrastructure may have overwhelmed it, contradicting Duffy’s account of the cause.
Calls for faster upgrades
The failure renewed calls for more funding to accelerate upgrades to the air traffic control system’s aging telecommunications equipment. The system’s outdated technology has now experienced another widespread failure.
