Overview Following the successful automated migration of all DBaaS PostgreSQL clusters to our v2 infrastructure earlier this month, IONOS Cloud is proceeding with the final decommissioning of the legacy PostgreSQL API v1. The API v1 endpoints will be permanently disabled. Once disabled, any programmatic requests made to the v1 API will be rejected.
Impact & Required Actions Because your underlying clusters have already been migrated, your databases will experience zero downtime during this API shutdown. However, you must ensure your management tools are updated to avoid disruption to your deployment workflows: - Endpoint Update: Ensure all scripts, Terraform configurations, and SDKs are pointing exclusively to the regional API v2 endpoints. - Authentication Switch: PostgreSQL API v2 does not support BASIC authentication. If you have not done so already, you must immediately switch your API and SDK authentication to TOKEN authentication.
API v2 Benefits Reminder Migrating your tooling to API v2 grants you access to the new platform features: - Regional Endpoints: Lower-latency API access routed directly to your specific region. - Observability Integration: Access to forward cluster logs and metrics directly to IONOS Logging and Monitoring. - SSD Premium Infrastructure: Full management capabilities for the upgraded, high-performance SSD Premium storage tier.
