In progress
The scheduled database maintenance window is starting now.
# Impact
During the maintenance and recovery, customers may experience the following:
- Running workflows and scheduled sessions delay and failure
The execution of running workflows and scheduled sessions will be delayed and automatically retried after the downtime period. However, there is a possibility that some workflows and sessions fail under certain situations.
- Workflow REST API will be unavailable
It won’t be possible to create or update Workflow Project, CDP Master Segments, Batch Segments, API Tokens, and Predictive Scoring during the downtime period.

Beyond this notice, we will provide updates at the start and completion of the operation, and once the verification of the new system is completed. At that time, all systems will have returned to full functionality and this Scheduled Maintenance will be closed.

Scheduled
On Thursday, February 3rd from 7:40 PM to 8:10 PM PST (February 4th from 3:40 AM to 4:10 AM UTC) we will be performing maintenance on the database underlying the Workflow component. This maintenance window is scheduled to perform essential maintenance on the underlying hardware. The database instance will be unavailable for the time it takes the failover to complete, usually about 60 seconds in total.
Although the maintenance window duration is 30 minutes, the database will only become unreachable for an expected maximum of 3 minutes in total. We expect this to be followed by a recovery period of around 10 minutes during which the system will gradually return to full throughput.

# Communication
Beyond this notice, we will provide updates approximately 1 hour before the beginning of the maintenance window, at the start and completion of the operation, and once the verification is complete. At that time, all systems will have returned to full functionality and the Scheduled Maintenance will be closed.
