As I understand it, a solar storm (which is what the article talks about - clickbait title should be edited) would primarily affect a) satellites b) things with long wires on earth, i.e. the power grid and copper communications. Not sure how undersea cables that have copper for amplifier power would be affected (e.g. whether water shields from this or not). To my knowledge, computers should not be directly affected (but may be affected by power grid fluctuations, which shouldn't affect computers on ships). Ships themselves should be largely unaffected aside from losing access to GPS if the satellites were destroyed. I assume that would disrupt shipping to some extent but not sure how much. Navigating without GPS is possible but less accurate and more time-consuming. It's also unclear if GPS satellites would be affected at all. Their orbit is high enough that changes to the atmosphere shouldn't affect them, and I'm not sure if the increase in solar radiation would be expected to destroy them or not.
