Hello,
I’m not sure whether you are referring to used storage or total available storage. However, if it’s used storage, this may be a case where the bin logs were purged. However, to know for a fact, this issue requires someone from the support team to inspect your instance. I would recommend you to contact GCP support as they can surely provide you with information about this storage reduction you are seeing on your instance.
