.. _arch_overview_load_balancing_overprovisioning_factor: Overprovisioning Factor ----------------------- Priority levels and localities are considered overprovisioned with :ref:`this percentage `. Envoy doesn't consider a priority level or locality unavailable until the percentage of available hosts multiplied by the overprovisioning factor drops below 100. The default value is 1.4, so a priority level or locality will not be considered unavailable until the percentage of available endpoints goes below 72%.
