# Failover routing Failover routing lets you route traffic to a resource when the resource is healthy or to a different resource when the first resource is unhealthy. The primary and secondary records can route traffic to anything from an Amazon S3 bucket that is configured as a website to a complex tree of records. For more information, see [Active-passive failover](dns-failover-types.md#dns-failover-types-active-passive). You can use failover routing policy for records in a private hosted zone. For information about values that you specify when you use the failover routing policy to create records, see the following topics: + [Values specific for failover records](resource-record-sets-values-failover.md) + [Values specific for failover alias records](resource-record-sets-values-failover-alias.md) + [Values that are common for all routing policies](resource-record-sets-values-shared.md) + [Values that are common for alias records for all routing policies](resource-record-sets-values-alias-common.md)
