From the doc:

It said when the upstream reached max_fails within fail_timeout and it will become dead. What if my server is up sometimes after?

In general,

  1. If a upstream server failed, will nginx retry with another server in the pool?

  2. Any variable I can configure so that they will join the pool automatically when they are up?

The documentation you linked to states that nginx will try the upstream again after fail_timeout seconds, to see if it has come back up.
