Nginx configuration

http {
  upstream alert {
    # fail_timeout=0 means we always retry an upstream even if it failed
    # to return a good HTTP response

    # Unix domain servers

    server unix:/tmp/hnalert_2.sock fail_timeout=0;

    # Unix domain sockets are used in this example due to their high performance,
    # but TCP/IP sockets could be used instead:
    # server 127.0.0.1:8081 fail_timeout=0;
    # server 127.0.0.1:8082 fail_timeout=0;
    # server 127.0.0.1:8083 fail_timeout=0;
    # server 127.0.0.1:8084 fail_timeout=0;

Elaborate a little more. Why is it wrong? What is happening and what do you expect to happen?
