We will be performing scheduled maintenance as part of the mandatory AWS RDS minor version upgrade activity. During this maintenance window, the CultureGrams Usage Statistics functionality will be temporarily unavailable. The downtime is required to upgrade the cg-usagestats RDS database, as Amazon is ending support for the current RDS minor version. Note: The rest of the CultureGrams application is expected to remain available.
