Start Time: 06 Jun 2026 02:00 UTC
End Time: 07 Jun 2026 08:00 UTC

Regional Cluster Schedules :

Projected Impact:
1. Customers who have created hard-coded dependencies for Regional Edge site may encounter a service interruption during this window.
2. Services and applications should remain unaffected and will continue to be served from other Regional Edges within the same region.
3. The tunnel from the Customer Edge (CE) to the Regional Edge (RE) will be unavailable, resulting in delays in propagating user configurations. However, the secondary tunnel will remain operational.
Rest assured, Customer Edge (CE) services and applications will not experience any downtime during this maintenance window.
4. We advise all F5 Distributed Cloud customers to configure staging settings for attack signatures and establish WAF exclusion rules for signatures associated with load balancers.

Reason for Maintenance:
This maintenance will implement updates designed to improve system stability and performance. To ensure consistent operation, a brief component restart will be required.

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