This topic describes how to modify the information about an origin server in the Dynamic Route for CDN console.
Background information
DCDN supports switchover between primary and secondary origins. If multiple origins are specified, DCDN forwards requests to the origin whose Priority is set to Primary. If the primary origin fails the health check three consecutive times, DCDN forwards requests to the origin whose Priority is set to Secondary. If the primary origin passes the health check, the system marks the origin as available and restores the priority of this origin to Primary. If you set the same priority for all origins, DCDN polls each origin.
