We will be performing minor PostgreSQL database engine upgrades in our Aurora clusters across all data centers.
This process requires a database server restart and failover, therefore there will be up to five minutes of disruption. We will upgrade each data center one at a time and will begin the first upgrade shortly after 07:00 UTC. We expect the upgrades to be completed by 09:00 UTC on Sunday, 30th November 2025.
We will provide notifications as this maintenance progresses via our status page.
