Universal Postal Union
- Single Postal Territory history: The postal system is the moment when human delivery becomes a network abstraction. A sender no longer needs to hire and supervise one carrier across the entire route. The institution accepts an addressed item, decomposes the journey into stages, manages handoffs and delivers through rules shared by strangers. This is a profound information transition. The post standardises destination, custody, routing, priority and exception handling. It also centralises metadata and control. Later electrical and digital networks accelerate the payload, but their architecture remains haunted by the old postal ghosts: addresses, packets, routes, forwarding, mailboxes and delivery failure
