Start Time: 18 Jun 2026 21:00 UTC
End Time: 19 Jun 2026 05:00 UTC

Projected Impact:
Routed DDoS customers may experience a slight increase in latency for traffic that is under active mitigation. Traffic volumes displayed in the F5 Distributed Cloud Console may appear lower than usual during the maintenance window — actual traffic will not be affected. Reporting will return to normal once maintenance is complete.

Reason for Maintenance:
Scheduled upgrade to the DDoS mitigation system to improve performance and resilience.

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