For the reasons already given by others, I do not believe that any cyber attack was involved in THIS outage which looks like simple bad luck in that two major sources of supply were lost within a few minutes. This has happened before, but not for over ten years.


I am however concerned at the vulnerability of the grid to any future cyber attack, and hope that the absence of any cyber attack THIS TIME does not result in complacency and a lowering of defences.


And as for the substantial problems caused on the railways, I blame this on the trend towards greater complexity. More to go wrong. More reliance on centralised control of signalling and over complicated new trains that need a specialist to re-start them after "computer says no"
