We will be performing maintenance on TigerData services in the following regions:

• ap-northeast-1
• eu-central-1
• eu-west-1
• us-east-2
• us-west-2
• az-eastus2
• az-westeurope

The maintenance period will begin on 2026-03-16 at 6:00 AM UTC and conclude on 2026-03-23 at 6:00 AM UTC.

During this time:

• Instances will restart within their scheduled maintenance window.
• No action is required.
• Services with HA replicas will not experience downtime but will undergo a single switchover event during maintenance, lasting only a few seconds.
• To prevent downtime during this event, consider adding an HA replica to your service.

As part of this maintenance, a new minor version of PostgreSQL will be installed. The corresponding minor version for your current major version will be applied.

Minor versions included in this update:

• 18.3
• 17.9
• 16.13
• 15.17
