      Note

      • Origin fetch policy: 100% of origin fetch traffic is first directed to the primary origin server. If an origin server fails three consecutive health checks, 100% of the traffic is directed to the secondary origin server.

        If an active health check is successful, the origin server is marked as available and its priority is restored. If all origin servers have the same priority, CDN automatically uses round-robin for origin fetch.

      • Origin server health check: CDN performs active Layer 4 health checks on origin servers every 5 seconds.

    5. After the configuration, CDN will use round-robin routing across all configured origin servers during content fetching. Therefore, ensure that the content on each origin server is consistent. Otherwise, the data retrieved by CDN may be inconsistent.
