DHS Secretary Mullin: No Cyberattack, FAA System Failure Unrelated to Microsoft Outage

The value here is in the official separation of two incidents that surfaced close together: an FAA system failure and a Microsoft outage, with DHS explicitly ruling out both a cyberattack and any link between them. That distinction matters for how the aviation and cloud-infrastructure sectors are read, since conflating the two would imply a shared technical or adversarial cause that the department says does not exist. The investigation remains open, so whether the FAA failure is traced to an internal systems issue is the question worth watching.
