Planned Maintenance Notification for F5 Distributed Cloud DNS Service – Global – Impact: Config Propagation Delay

Scheduled for Apr 18, 04:00 - 10:00 UTC

Scheduled

Dear Valued Customers,

We would like to inform you of an upcoming Planned maintenance activity that will be performed on the following F5 service:
- F5 Distributed Cloud DNS Service

Maintenance Window:
Start Time: 18 Apr 2026 04:00 UTC
End Time: 18 Apr 2026 10:00 UTC

Reference: SDCCAB-3534

Projected Impact:
During this upgrade window, any DNS record–related operations such as primary zone creation, secondary zone creation, and zone updates will remain in a pending state until the upgrade is completed and the Kafka service is fully operational. Once the upgrade is complete, these operations will be automatically retried and will move to an active state. There will be no impact to other traffic flows.

Reason for Maintenance:
We need to prepare DNS kafka for any zonal failures. So we will be applying HA configurations during this period.

Our Commitment:
We will provide timely updates should there be any changes to the schedule or if unexpected issues arise.

- Email Support: Reach us at support@cloud.f5.com for any questions or assistance.

Sincerely,
F5 Distributed Cloud
