Thank you for your interest in the service load balancing policy (serviceLbPolicies) feature.
Currently, service load balancing policies are affected by a known issue where traffic might not be evenly directed to all VMs in a particular zone. You can fill out this form to be allowlisted for an early fix for this issue. Note that you can still try out service load balancing policies whether you are on the allow list or not.
Once you fill out this form to sign up for the early fix, we will get back to you within two weeks if you are eligible. If not, we will notify you when service load balancing policies are available in GA.
As always, we don't recommend running Preview features in production. Moreover, please review the known limitations.
Thank you,
Service Lb Policy team
