Health Check Status Information

Applies To:

RouteThis platform is designed to provide reliable, high performance, and secure DNS service. This DNS service consists of zone administration, traffic management, and custom routing policies.

Health ChecksThe DNS Health Checks module checks the health of a server or domain by polling it with an HTTP or TCP request. These health checks are essential when load balancing or failing traffic over multiple servers.

An icon will appear next to each monitored server indicating its current status. A server's health check status is determined by a simple majority consensus. The following table provides a list of icons and their definitions.

Icon	Label	Description
	Success	Indicates that a majority of our health check agents have successfully verified that the monitored server/domain is healthy.
	Failed	Indicates that a server/domain failed a majority of its health checks. Our DNS service will not serve traffic to servers/domains in this state.
	Admin Down	Indicates that the server/domain has passed a majority of health checks, but traffic will not be directed to it as a result of a load balancing or failover configuration. The most common scenario for this state occurs when a server/domain configured for manual reintegration has recovered from a failed health check state but has not been reintegrated into a traffic management configuration.
	Unknown	Indicates that our health check agents are unaware of the server/domain's health state. This state occurs when a new health check configuration has been established. Once our health check agents make a decision on health status, a new status will be assigned to it.
