Customer Impact

This will be an underlying internal database migration which is not exposed to customers directly. It will be performed over the weekend to minimize disruption. While no customer impact or downtime is expected, there could be 10 to 20 minutes of downtime limited to a single pod, affecting Support, Guide, Talk functionality, and certain Apps. The rollout will be halted if the migration does not go as planned.
