Done for me in prod but I 've got a problem with this conf.
If  I stopped b3 backend got an error 503 and no failover

....
backend b3 {
     .host = ".....";
     .port = ".....";
     .probe = {
                .request =
                "GET / HTTP/1.1"
                "Host: ..."
                "Connection: close";
                .timeout = 1s;
                .interval = 5s;
                .window = 4;
                .threshold = 2;
     }
}


backend b4 {
     .host = "...";
     .port = "...";
     .probe = {
                .request =
                "GET / HTTP/1.1"
                "Host: ...."
                "Connection: close";
                .timeout = 1s;
                .interval = 5s;
                .window = 4;
                .threshold = 2;
     }
}

sub vcl_fetch {
        set obj.grace = 30s;
        if (obj.ttl < 600s) {
                set obj.ttl = 600s;
        }

        if (obj.status != 200 && obj.status != 302 && obj.status != 403 
&& obj.status != 404 ) {
                restart;
         }

}

sub vcl_recv {

 set req.grace = 30s;

 if (req.url ~ "/dir") {
               if (req.restarts == 0) {
                       set req.backend = b1;
                } else {
