Power spikes & surges
This is something on a much, much smaller scale than the BA fiasco!
I'm the organist at the kirk on Stronsay, a tiny island in Orkney. Our new electronic organ arrived 4 years ago and behaved well until about 12 months ago. Since then it has had frequent "seizures" which made it unplayable for about 24 hours after which it behaved normally. Speaking to an agent of the manufacturer he asked if we had many solar panels or wind turbines. I replied that we did and the number was growing quite quickly. He said that these gadgets create voltage spikes which can affect delicate electronic kit and recommended a "spike buster" mains socket. Since fitting one of these the organ has behaved perfectly. I suspect that with the growing number of wind turbines & solar panels this sort of problem will become more and more noticeable
