跟进：达菲称全美停飞源于一台路由器灌爆空管网络，22个航路管制中心17个受影响，周六逾5000个航班取消

美国交通部部长 Sean Duffy 与美国联邦航空管理局（FAA）局长 Bryan Bedford 于11月14日上午在华盛顿举行记者会，公布11月13日全美地面停飞的初步调查指向：承包商 L3Harris 在一处偏远设施进行例行维护、把通信线路从铜线更换为光纤时，一台路由器向空中交通管制网络灌入大量连接请求，全美22个航路交通管制中心中有17个受到影响，FAA 随即下令全美停飞。两人均表示，没有证据显示这起故障与网络攻击或超级智能（SI）有关。

FAA 代理首席技术官 Rebecca Guy 在记者会上说，网络出现不稳定后，技术人员发现两处节点以每4到5秒约1,000次连接的速率向网络发送请求，FAA 立即停用了这两处节点，网络随即恢复稳定，目前正在进行根本原因分析。Duffy 说，究竟是 L3Harris 的人员操作或安装失误，还是这台路由器本身有缺陷，目前尚未查清，查清后将追究责任。L3Harris 向 CNN 发表声明称，正配合 FAA 调查这起导致11月13日全美停飞的事件，并严肃对待事件对旅客、航司与空管运行的影响。

Bedford 说，受影响设施最多时达17个，各设施的通信频率时断时续，管制员被迫在主用与备用频率之间切换，但没有任何一处设施完全失去信号。他说，如果只有一个设施出问题，FAA 本可以逐个处置；当受影响设施从两个、三个增加到十个、十七个时，局方意识到这是系统性问题，遂下令全国停飞。Duffy 说，全美仍有约三成铜线尚未更换为光纤，交通部正排查其余铜线的位置，并将重新评估这类更换作业的时段安排。

停飞的影响延续到周六。据航班追踪机构 FlightAware 统计，截至美东时间周六下午1时，全美周六已有超过5,000个航班取消、4,400多个航班延误。Bedford 在记者会上估计，周六预定的约41,000个航班中可能多达5,000个被取消，航司需要重新调配飞机与机组；他说最坏的阶段已经过去，预计周日实现全面恢复。Duffy 在记者会上再次呼吁国会增加对空管系统的投入；众议院议长 Mike Johnson 同日对 Fox News 表示，共和党人将在本届国会剩余50天内推动为 FAA 增加拨款授权。

Follow-Up: Duffy Says a Single Router Flooded the Air Traffic Network in the Nationwide Ground Stop; 17 of 22 Centers Affected, Over 5,000 Saturday Flights Canceled

U.S. Transportation Secretary Sean Duffy and Federal Aviation Administration (FAA) Administrator Bryan Bedford held a press conference in Washington on the morning of November 14 and laid out the preliminary findings on the November 13 nationwide ground stop: while contractor L3Harris was performing routine maintenance at a remote facility, switching communication lines from copper wire to fiber, a router flooded the air traffic control network with connection requests, affecting 17 of the nation's 22 air route traffic control centers and prompting the FAA to order the nationwide ground stop. Both officials said there was no evidence the failure was linked to a cyberattack or to super intelligence (SI).

FAA acting chief technology officer Rebecca Guy told the press conference that after the network became unstable, technicians found two locations pinging the network at a rate of about 1,000 connections every four to five seconds; the FAA disabled both right away, the network stabilized, and a root cause analysis is now under way. Duffy said it has not yet been determined whether the fault was user or installer error by L3Harris or a defective router, and that those responsible would be held accountable once the cause is established. L3Harris said in a statement to CNN that it is supporting the FAA's investigation into the conditions that led to the November 13 ground stop and takes the impact on travelers, airlines and air traffic operations seriously.

Bedford said as many as 17 facilities were affected, with frequencies going in and out and controllers forced to switch between primary and backup frequencies, but none of the facilities actually went dark. He said that if a single facility had been affected, the FAA would have worked through it; when the count rose to two, three, 10 and then 17 facilities, the agency realized it was facing a much larger problem and ordered the nationwide stop. Duffy said about 30 percent of the nation's copper wires have yet to be replaced with fiber, that officials are working to identify where those lines are, and that the timing of such switchover work will be reevaluated.

The disruption carried into Saturday. According to flight tracking service FlightAware, as of 1 p.m. Eastern Time on Saturday, more than 5,000 flights had been canceled across the United States on Saturday and more than 4,400 were delayed. Bedford told the press conference that as many as 5,000 of the roughly 41,000 flights scheduled for Saturday could be canceled as airlines reposition aircraft and crews; he said the worst is behind us and that full recovery can be expected on Sunday. Duffy again called on Congress to invest further in the air traffic control system, and House Speaker Mike Johnson told Fox News the same day that Republicans would use the remaining 50 days of their House majority to authorize more spending on the FAA.
