The SpacetimeDB Cloud version runs with distributed replication, so it continues to be available on the other nodes.
On the SpacetimeDB Standalone (single node) version, you lose your data, same as you would with Postgres or Sqlite.
So, in short, I think I agree with the op:
> I don't see anything that indicates how spacetime solves the core problem CRDB does, which is guaranteeing that single node failures can be tolerated with zero data loss or loss of availability
