 Unknown or stale occupancy, stopped or unhealthy members, active betas, campaigns, maintenance, host drains, and unresolved recovery hold the policy's decisions. Autoscaling does not repair these conditions itself. The page and linked Provisioning operation explain the current blocker, including capacity and game key waits.

Empty intervals reset when players arrive, evidence becomes unknown, the instance or lifecycle changes, or observation continuity breaks. Controller downtime does not count toward the empty duration. Failed or uncertain automatic operations pause further actions until an operator inspects their Provisioning recovery and reviews the policy again.
