    On the topic of solar flares and the potential for communication disruptions, there has been one major historical example, in September of 1859 there was a solar storm so intense that it caused telegraph lines to short out around the world, and the Northern lights to be seen as far south as Hawaii. Since then there have been numerous lesser examples, with isolated and regional outages, but few have occurred in last 40 years. So like many things in nature it is just a matter of when, not if.
