Load Balancing: Traffic sent to an origin with "0" weight?

Expected Behavior

Setting "0" as a weight for an origin should result in no user traffic for that Load Balancer being sent to that origin. Health Checks will still be sent at the expected interval.


The following conditions will cause traffic to still be sent to that origin:

Origin is Used in Other Pools

If an origin is used in another pool, it may have a multiple weight values assigned to it and traffic will be distributed to the origin based upon a different pool and load balancing configuration. You can check your origins in the Traffic App or via the List Pools API to identify if that origin is being used in multiple configurations.

Grey-cloud Load Balancer

Currently, weights only apply to orange-cloud Load Balancers only. Grey-cloud load balancers will ignore weight and round robin traffic evenly amongst the configured and active origins.
