I realise full well that the media sensationalizes everything, but no smoke without fire. We have already had a Christmas terror attack here and I expect some attempts over New Year. The dude with the weird haircut (not trump - the other one) makes all sorts of threats and if there is any truth at all in the press, he seems a few sandwiches short of a picnic. China and pushing at the edges of its borders and seems quite prickly, Russia seems to be teasing everyone. A few more natural disasters will make things even more tense. I do not expect WW3 but I do expect some disruptions, in Oz we are overly dependent on fuel shipments which can be easily disrupted. This would lead to petrol rationing, which would also affect deliveries of anything from food, fuel itself, the coal trains that take coal to our power generators are diesel powered, I have been through power rationing before. Not talking about the likelihood of these things happening, just if they did. How would you be affected? Communications? Transport/travel/water supply and so on. I have designed computer systems and networks, we build in redundancy, back up power supplies, multiple CPUs, multiple drives storing the same data, something dies, the system continues, often with no noticeable effect. What is your plan "B"?
