The Unstable Nature of Onion Networking

When you access an onion site, your connection bounces through three different volunteer nodes - this process protects your identity but it also makes the connection fragile. If the person hosting the site loses their internet connection or their hardware fails, the site vanishes instantly. Because there is no central authority to manage these addresses, there is no "customer support" to call when a link stops working.
