I have no experience of this sort of thing, so excuse the naivety of my question... In the course of the last few days, our house has experienced at least six electrical items failing. This includes a network router and a set of speakers, both of which stopped working sometime during Sunday night. Countless other devices have failed since then, including a Sky+ satellite box, an electric fly catcher, a wall heater... I know all this could just be bad luck and we're seeing a pattern where there isn't one, but could there be anything that could have caused these apparently unrelated faults? We use surge protectors to protect our computers, yet the speakers and network router failed at some point in the middle of the night.
Again, apologies if this sounds naive but I'd like to know if I'm just being paranoid before I call an engineer in to chase these ghosts... :-)
