We want to inform you of a disruptive change of about 15 minutes in the window scheduled for your deployment(s) as follows:

AWS - US West (Oregon) 10:00 - 12:00 PDT May 2, 2020

Snowflake engineering is making changes to the AWS - PrivateLink configuration to improve performance and operational efficiency.

Configuration Change:

This maintenance update requires a downtime of approximately 15 minutes.
During this maintenance window, customers using AWS - PrivateLink cannot connect to Snowflake Services. Client programs or workloads with connections established before the start of the maintenance window are dropped and require a restart after the maintenance task is complete.

Configuration Rollback:

We have tested the changes thoroughly. However, if we do encounter problems, we plan to roll back the change and restore the state of the network configuration. This operation will require a downtime of approximately 10 minutes.

Customer Action:
Please monitor Status Page notifications for “Maintenance Complete” status update
Resume your operations and restart the workloads as needed

Snowflake Status Page will send a reminder one hour before the start maintenance task. We will send another announcement after the task is complete.

Note: Please note that the service will be down only for a portion of the window of 2 hours mentioned above.

Please reach out to customer support by opening a support case on the Snowflake Community site for any questions regarding this change to AWS - PrivateLink configuration.

Thank you,
Snowflake Support
