Dear list,

Here's my current config:
http {
upstream ups {
server 192.168.90.100;
server 192.168.91.110 backup;
}
server {
listen 80;
server_name localhost;
location / {
proxy_pass http://ups;
}
}
}
It shows that when main server (192.168.90.100) is down, it took at least 10
seconds to get response from backup server (which almost instant when main
server up). I wonder how can I reduce this delay?

TIA,
