据彭博社报道，FBI正在调查周五导致全美航班停飞的故障是否由软件更新引起。彭博社援引一名知情人士的话说，该局不认为这是网络攻击或犯罪所致。
he FBI is looking at whether a software update caused Friday’s outage that grounded flights across the US, Bloomberg reported. The bureau does not believe a cyberattack or crime was behind it, Bloomberg said, citing one person familiar with the matter.
据半岛电视台报道，联邦航空管理局（FAA）在周五因故障切断其管制中心通联后，下令所有航班停止起飞。停飞持续了四个多小时，波及所有22个管制中心，这些中心负责引导飞机在机场间飞行。
The Federal Aviation Administration stopped all flights from taking off on Friday after a fault cut links at its control centres. The halt lasted more than four hours and hit all 22 centres, which guide planes between airports, Al Jazeera reported.
这是自2023年1月FAA计算机系统故障以来首次出现此类停飞。数千航班延误或取消，连锁影响预计将持续整个周末。
It was the first such halt since January 2023, when an FAA computer system failed. Thousands of flights were delayed or cancelled, and the knock-on effects are expected to last all weekend.
官方尚未给出原因。不过，多位消息人士告诉哥伦比亚广播公司（CBS News），连接空管系统的专用网络进行了一次更新，导致其重启后崩溃。
No official cause has been given. However, multiple sources told CBS News that an update to the private network connecting the air traffic control system made it restart and then crash.
交通部长肖恩·达菲将责任归咎于老旧设备。据Axios报道，他在周五晚间的一个新闻活动上表示，老旧系统被数据淹没后失效。
Transportation Secretary Sean Duffy blamed old kit. At a press event on Friday evening, he said ageing systems had been flooded with data and failed, Axios reported.
国土安全部长马克韦恩·马林表示，官员正在核查新旧设备是否未能协同工作。他表示没有网络攻击的迹象。
Homeland Security Secretary Markwayne Mullin said officials were checking whether old and new kit had failed to work together. He said there was no sign of a cyberattack.
据哥伦比亚广播公司报道，马林还表示，此次停飞与同一天发生的另一起全球性微软故障无关。
Mullin also said the outage was not linked to a separate global Microsoft outage on the same day, CBS News reported.
FAA正在更换其大部分空管技术。据报道，它于9月开始在华盛顿地区使用一款AI拥堵管理工具，但没有任何消息来源将该系统与周五的故障联系起来。
The FAA is replacing much of its air traffic tech. It began using an AI congestion tool around Washington in September, though no source has linked that system to Friday’s failure.
