Regarding maintenance activities:
- Scheduled upgrade of the message broker system will require a restart of backend services, resulting in a brief service interruption during the maintenance window.
- Selected Kubernetes worker nodes will be decommissioned and replaced with updated infrastructure to maintain cluster performance and reliability.
- Kubernetes nodes hosting Pgbouncer services will be migrated from current hardware to new ARM-based servers to optimize performance and resource utilization.
- Database server configuration will be updated to adjust CPU, memory, or storage resources to meet current performance requirements.
- The ingress controller will be updated to the latest version using a rolling upgrade strategy, ensuring zero downtime and uninterrupted service availability.
Please refer to our Maintenance Event Schedule for further information regarding the date and times for regional maintenance windows.
If you have any questions about the maintenance windows please reach out to your Customer Success Manager or the Tulip Support Team
