 Service availability encompasses both unintentional and intentional downtime of endpoints behind a load balancer. Several factors can contribute to unintentional downtime, including hardware failure, software bugs, network issues, and ISP or other vendor issues. Even for the most advanced organizations, these issues are inevitable.
 
-Load balancers solve these issues by always monitoring the health of endpoints. If an endpoint is slow to respond to a health check, or fails to respond entirely,the endpoint is marked as unhealthy. Several methods exist for doing so, including basic health tests like ICMP (ping) and TCP connection tests. More advanced health tests can be used like issuing an HTTP GET request and ensuring a specific response code and response body are returned from the endpoint. Once an endpoint is in a degraded state, the load balancer will send fewer or no requests its way in favor of healthier endpoints. As the endpoint becomes operational again and the load balancer is able to receive responses to its health checks, the endpoint is marked as operational and has traffic steered towards it once more.
