High latency one of IPS

Hello,
I have site and one of load balancing IP is located in Vienna - when client resolves to that IP, everything is fast. But when DNS client hits ip located in Singapore latency and packetloss goes thru the roof. Can I somewhat modify second load balancing IP? Currently I am getting 104.21.82.48 and 172.67.153.106 as CF proxies. I am currently using free tier.
