The default proxy module timeouts are pretty high (like 60s)

http://nginx.org/en/docs/http/ngx_http_proxy_module.html#proxy_connect_timeout
http://nginx.org/en/docs/http/ngx_http_proxy_module.html#proxy_read_timeout

... so naturally if the backend doesnt respond in timely matter it can take
up to a minute for nginx to decide what to do next.


I would also rather than using (with dns resolve):

location / {
proxy_pass https://some.site.com;
}


choose the upstream module (
http://nginx.org/en/docs/http/ngx_http_upstream_module.html ) and define all
the backends in the upstream {} block:

upstream someservers {
server your.backend1.ip:80;
server your.backend2.ip:80;
server your.backend2.ip:80;
}

location / {
proxy_pass http://someservers;
}
