Failover Group Modification

Common reasons for updating a failover group are to:

• Modify an IP address or domain. This is the quickest method to point a failover group to a different server/domain.
• Designate a different primary server/domain. Setting up a different primary server/domain will redirect all traffic to it.

• Remove a server/domain from a failover group. Keep in mind that a failover group must have exactly two:

  • IP addresses of the same type (i.e., IPv4 or IPv6)
  • CNAMEs
• Add, modify, or delete the health check configuration associated with an IP address/domain.
• Reintegrate a server/domain back into a failover group. Our DNS service will not serve traffic to a server/domain 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.

• Modifications to a failover group will not be saved until Submit Group is clicked.
