   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.
