作为网络工程师或者运维工程师，我们对于traceroute命令一定不会感到陌生。这个命令类似于ping命令，用于诊断网络的连通性，但traceroute命令输出的信息更加详细，可以帮助我们跟踪从源系统到目标系统的路径。

Illustration: The Verge Overnight, many people reported on social media that they were inexplicably logged out of their Apple IDs and then required to reset their passwords when they tried to sign in again, and nobody seems to know why. Some reported needing to enter their iPhone passcode to connect to iCloud again, while others with Stolen Device Protection enabled said they had to wait an hour before being able to log in. Apple’s System Status webpage shows no current issues with any of its services, so it’s not clear if this was a widespread issue. That said, 9to5Mac reports that even a few of its staff members were also affected by the issue. At least one Forbes contributor apparently experienced the issue as well.
