Why We are Performing Maintenance
We regularly perform infrastructure maintenance to:
- Improve the performance and reliability of our services.
- Implement new features and functionality.
- Address security vulnerabilities.
What to Expect
During this maintenance window, there will be no interruptions to your application access to data. However, you may experience brief service interruptions to new volume provisioning functionality. Specifically, you may experience a temporary impact on provisioning if you have an impending completion of a volume deletion. If a new application volume provisioning fails during this time, you can simply retry the operation.
We have intentionally scheduled this maintenance during times of lower activity to minimize disruption, and our team will work to complete the process as efficiently as possible.
What You Can Do
If feasible, please arrange for any critical tasks that require new volume provisioning to be scheduled outside of the maintenance window.
Thank you for your understanding as we work to provide you with a more dependable and secure service. If you have any questions or concerns, please reach out to the Google support team.
Duration: 5 hours
Best,
Google Cloud NetApp Volumes Team
