How Does Origin Pull Work If Origin Servers Have Multiple IP Addresses?

If the origin servers have multiple IP addresses, the following load balancing mechanism is used for origin pull.

An origin pull request can be forwarded to up to two IP addresses of the origin server with highest priority. If origin pull from both IP addresses fails, the request is forwarded to an origin server with a lower priority. The request can be forwarded to up to two IP addresses of the second origin server. If origin pull fails again, the request fails.
Origin pull fails when the connection times out, the connection fails, or a 5xx error code is returned from the origin server.
