Load Balancing Group Modification

There are a variety of reasons for updating a load balancing group, such as:

• Add or remove servers or CNAMEs from the group.
• Change the load balancing weight assigned to a server or a CNAME.

• Add, modify, or delete the health check configuration associated with an IP address or a CNAME.

• Reintegrate a server/CNAME back into a load balancing group. Our DNS service will not serve traffic to a server/CNAME that has failed a majority of health checks. The health check configuration defined for that server or CNAME determines whether manual intervention is required to indicate when our Route name servers can resume serving traffic to it.
