This doesn't imply anything about load balancers not working. Load balancers work by creating what are called VIPs - virtual IPs, which aggregate the IP addresses of the balanced services. In a lot of cases, the individual services need not even be routable from the public internet as long as they are reachable from the load balancer's internal interface. (edit: fixed a typo)
