Non-random thought: It wasn't a cyber-attack.

Why do I say that? --Because it's the excuse that the press is reporting.
I was in security forensics for a while. No computer hack can cause the disruption for so long. Most critical infrastructure has plans and back up that could erase every line of code and data and reload to be back up and running in 48 hrs. This makes no sense.
It’s only important what the masses will believe, not what the real experts know.
