Will the site work if some processes are not running?

Question

Nginx

There is this part of the nginx configuration:

upstream my_site {
    server   unix:/tmp/thin_demo_1.0.sock;
    server   unix:/tmp/thin_demo_2.0.sock;
}

The question is, if the thin_demo_2.0.sock process is killed and does not work, then everything will function normally? nginx won't direct users to this process? Or is it better not to do this and keep all processes running?
Do not ask why I need it)) Just need it.

Answer 1

Depends on other settings, but in general every second request will not work.
If you need to turn off the server and at the same time leave it in the list, there is a down flag in the settings
