Think they'd tell us if that was in fact the case, ie a Russian or Chinese hack just testing the waters?"The outage comes as a result of the failure of the FAA's NOTAM (Notice to Air Missions) system". The FAA has now ordered a ground stop across the country. It is not known when the system will be restored.
It is not clear yet if this system failure was simply due to a hardware/software fault or due to malicious hacker activity.

We'll know more if the lights go out later I guess.
