There's no guarantee that any of these relays we are using today will even still be running in just 10 years. I want a paid relay service that I can buy real data persistence on. One that will back up all of my notes with robust, redundant storage in multiple locations, preferably in multiple countries, on multiple continents. Maybe even one of those locations can be an orbital satellite. I want to buy 100 years of data persistence. If my descendents decide it's important to them, they can buy another 100 years of persistence.
