don't recall the specifics of the snippets I sent over, but the above is
correct, you do map definition at
map $arg_op $upstream_server {
        "stats" sks_servers_primary;
        default sks_servers;
}

which is used for

        location /pks/lookup {
    proxy_cache backcache;
        proxy_ignore_headers Cache-Control "Expires";

    #proxy_cache_bypass $http_cache_control;
    add_header X-Proxy-Cache $upstream_cache_status;
    proxy_cache_valid any 10m;
                proxy_pass http://$upstream_server;
                proxy_pass_header  Server;
                add_header Via "1.1 keys2.kfwebs.net";
                proxy_ignore_client_abort on;
        }
}
