High Availability is a feature in DrayTek dual and multi-WAN routers that automatically switches hardware, e.g. a standby router, when a primary router fails for whatever the reasons (loss of power, hardware failure, etc.).

High Availability is required wherever any networks outage causes significant losses or disruptions to the service level. For example, organisations such as government offices, company headquarters, hospitals, utility companies, data centres, etc., all need their network to be always available and not be affected by network disruptions.

This video provides an overview of High Availability in DrayTek routers as well as a demonstration of this feature
