An authorized entity or misconfigured lifecycle policy may transition objects from a high-durability or high-availability storage class to a lower-durability or single-zone class. This degradation manifests only when a subsequent failure occurs (e.g., availability zone outage). Objects may also be transitioned to archival tiers, rendering them effectively inaccessible for extended retrieval periods during incidents.
