Explanation
When a load balancer is configured in round-robin mode, it distributes traffic evenly across all of the servers in the pool. If new servers are added to the pool, they will not be operational until they have been configured and brought online. During this time, the load balancer will not distribute traffic to the new servers, which can cause the website to be intermittently unavailable.
