  2. identified Apr 13, 2026, 01:23 AM UTC

    The issue has been identified. Callbacks instances have been restarted following a lock of the services. Impact on callbacks success rate seems low due to retry mechanisms, only delayed dispatching. Downlink sequences have been impacted due to this delay. Backend portal is down but does not impact the connectivity services, messages are still processed.

  3. monitoring Apr 13, 2026, 04:18 AM UTC

    The downlink service and the backend have been restored. All services should be nominal. We are still closely monitoring the situation and will continue investigating on the root cause. A Problem Management process will be held, and an Incident Report will be communicated as soon as we have determined the root cause.

  4. resolved Apr 13, 2026, 12:13 PM UTC

    The incident is confirmed as Resolved after the monitoring period. We will continue investigating and proceed to corrective actions, and build a detailed Incident Report
