There's a brief mention of the load-balancer (nginx) in front of the Go servers; I'm curious if there's anything interesting happening there. I'd imagine that if you lose a server, all of the clients will try to reconnect and traffic will be spread across the existing servers. That's all find and good, but presumably when you bring up a new server to replace the failed on, it'll be seriously underutilized. Is there some easy solution here in nginx-land?
For websocket? Yes (https://github.com/SocketCluster/loadbalancer), but you would have to introduce another layer (AFAIK) that would detect failure and reconnect to a healthy target without informing the client.
