Decommissioning Public102 was an exercise in the mundane, gradually transitioning tiny service after tiny service to new homes over the course of weeks, as the development schedule allowed. Unfortunately, the network operations had a cruel surprise for us. You create a new server with the same software and add it to the load balancer.
