In a past life as a Police officer in a very remote and isolated town, we had a fibre cable severed which took out all telecommunications (fixed/internet/wireless - the works).
Besides myself, not a single office knew how to work the HF radio, which was our only lifeline to the outside world thanks to a broken sat phone.
Moral of the story is don't get complacent and forget how to use old tech, when the unexpected wipes out modern methods.
