The front-end of an application is an nginx server. All static content is processed by nginx, all PHP requests are distributed to several downstream servers running the PHP FastCGI daemon.

maximum number of failures is 3, which is 3 attempts, and the time-out is 30 seconds. The default value for Max_fails is 1, andthe default value for Fail_timeout is 10s. The case of a transmission failure, specified by Proxy_next_upstream or Fastcgi_next_upstream. You can also use Proxy_connect_timeout and proxy_read_timeout to control the upstream response time. One situation to note is that the max_fails and Fail_timeout parameters may not work when there is only one server in upstream. The p
