We’ve implemented adjustments to improve inbound call handling on the Orange Platform. Since these changes, we’ve observed a significant reduction in call failures, and service is currently performing near expected levels. Our investigation identified a hardware issue on one of the servers involved in certain call handling scenarios. Traffic has been redirected to redundant systems, which are currently managing call volumes effectively. While we do not expect widespread impact, intermittent call issues may still occur in rare cases until repairs are completed. Our team is actively working on restoring full system redundancy and will continue to monitor the platform closely.

Following our earlier adjustments and traffic redirection to redundant systems, we’ve continued to monitor inbound call handling on the Orange Platform. While the situation has improved, we are still observing some intermittent instability in certain scenarios. We’ve identified a specific hardware component contributing to the issue. Replacement hardware is scheduled to arrive overnight, and our team will move forward with installation as soon as it becomes available. This replacement is expected to restore full capacity and stability. We will provide a final update once the new hardware is in place and service levels have been fully validated.

The replacement hardware has been successfully installed and is now back in production. Inbound call handling on the Orange Platform has returned to normal, and system performance has been fully restored. We will continue to monitor the platform to ensure continued stability, but no further impact is expected at this time.
