FAA Rules Out Cyberattack, AI Involvement in Nationwide Ground Stop

Federal officials sought Saturday to quell speculation about what caused Friday’s unprecedented nationwide ground stop, insisting the disruption stemmed from an equipment failure rather than any cyberattack or artificial intelligence malfunction.“We see zero evidence of anything nefarious and zero evidence of anything AI-related. So we want to be clear that we have an equipment issue, and we’re working through what this defective piece of equipment was,” FAA Administrator Bryan Bedford said at a Saturday press conference.Mr. Bedford added that a full investigation is underway. “When we have that root cause analysis complete, we’ll share it with you,” he said.Transportation Secretary Sean Duffy, also speaking Saturday, echoed Mr. Bedford’s assessment, tracing the failure to routine infrastructure work at a remote FAA facility. “In at least one of our remote FAA locations, a contractor was doing routine maintenance to switch telecommunication lines from old copper wire, and they were bringing it over to fiber,” Mr. Duffy said.Mr. Duffy explained that the transition went wrong when a piece of equipment malfunctioned during the changeover. “Either through contractor error or a faulty piece of equipment, that router that was being replaced as we switched from copper to fiber, it started flooding other routers in our air traffic control system. So specifically, we had over 1,000 connection attempts every four to five seconds, and what that did was gave us issues with our communication with airplanes, and it also caused some disruption with our radar feeds,” he said.Mr. Duffy also noted that many of the routers in use today by the FAA were manufactured in 2001.The overload forced the agency to shut down affected airspace. “Once we were able to isolate the work that was being done at this remote location, all of our systems came back online, so we don’t believe this was cyber at all. This was an FAA system that didn’t meet the moment,” Mr. Duffy said.Not everyone is convinced. Anna Giaritelli, a national security reporter for the Washington Examiner, told CNN’s Laura Coates that air traffic controllers she has spoken with are skeptical of the official explanation. “None of them are buying what he said,” Ms. Giaritelli said, noting that routine switch-overs are typically scheduled overnight, not during a busy Friday afternoon.The Friday incident began around 3:36 p.m. ET, when instability in radar and communications systems prompted the FAA to halt departures nationwide “out of an abundance of caution.” Airspace reopened around 8:15 p.m. ET, but the fallout has lingered. More than 7,700 flights were canceled Friday, with over 8,000 delayed, according to FlightAware. Saturday brought further disruption, with more than 2,000 flights already canceled and 300 delayed.Mr. Duffy has used the incident to renew calls for a massive infusion of federal funding, requesting $50 billion from Congress to overhaul the nation’s aging air traffic control infrastructure, which he says relies on decades-old copper wiring and outdated switches. “This is an emergency. I want Congress to give us emergency funding,” Mr. Duffy said. “This is bipartisan. This is American. I want $50 billion.”As investigators work to pinpoint the exact cause, travelers should brace for continued disruptions. “I believe that it’s going to take us some time to get back to capacity,” Mr. Duffy said.Saturday’s press conference got off to a rocky start as technical problems with the audio system forced the officials to step back from the podium as a new microphone was brought in.
