On September 25, 2023 from 10:00 to 11:00 JST (September 25, 2023 01:00 - 02:00 UTC), the backend databases supporting the Treasure Data system will undergo a short maintenance.
# Impact During the maintenance window, the RDS backend databases supporting the Treasure Data Platform will undergo a MySQL version upgrade. During this time frame, despite the one-hour window, the databases will only become unreachable for no longer than 3 minutes in total. Customers will experience momentary failures, instabilities, or service unreachable for all services. As we approach the end of the maintenance, services will gradually return to their full throughput and operations.
# Communication Beyond this notice, we will provide updates approximately one hour before the beginning of the maintenance window, at the start and completion of the operation, and once the verification is completed. At that time, all systems will have returned to full functionality and the Scheduled Maintenance will be closed. If you have any questions or concerns about this maintenance, please feel free to reach out to our Support team at firstname.lastname@example.org.
