This incident has been resolved.

We have received confirmation from our vendor that the underlying issue has been remediated and continue to monitor for any recurrence. All geoproximity-based DNS resolution appears to be operating normally and PoP assignments have stabilized.

If you experience any further issues with geoproximity-based DNS resolution after reconnection, please contact FortiCare Support (https://www.fortinet.com/support/contact) and reference this incident.

We appreciate your patience throughout this event.

Reports of geoproximity-based DNS resolution issues have largely resolved. Latency for new endpoint connections has improved significantly as PoP assignment stabilizes, and we expect any remaining impact to fully self-resolve as this process continues.

For active cases still experiencing poor latency, we have a workaround available. Please contact support and reference this incident and our team can direct traffic to an alternate region while resolution completes.

We are working with our vendor on full resolution and on identifying improvements to prevent recurrence. We apologize for any inconvenience and appreciate your patience.

The third-party provider has implemented a fix and we are starting to see successful DNS resolution to allow managed endpoints to connect to their PoPs, with some potential for added latency. We are monitoring the results.
