  1. investigating Mar 03, 2026, 11:43 AM UTC

    We are currently investigating networking issues within the Link11 Backbone that are affecting multiple customers across different services. The impact may include partial packet loss, slow responses, or intermittent unavailability. At this stage, it is not yet clear which services are affected or whether the issue originates within the Link11 network or with external connectivity providers. Our engineering teams are actively analyzing the situation and working to restore stable connectivity as quickly as possible. We will provide further updates as soon as new information becomes available. Thank you for your patience and understanding.

  2. monitoring Mar 03, 2026, 12:40 PM UTC

    We have isolated the environment responsible for the recent connectivity issues and implemented a bypass to route traffic away from the affected segment. With this change in place, overall connectivity has significantly improved, and the previously observed disruptions should now be largely reduced or no longer present. Our teams continue to monitor the situation closely to ensure stability and identify any remaining anomalies. Thank you for your patience and understanding while we are working on this.

  3. resolved Mar 04, 2026, 09:47 AM UTC

    The connectivity issues impacting parts of the Link11 Backbone have been fully resolved. Following our previous mitigation steps, our engineering teams deployed a permanent fix to the affected systems. After implementing and verifying the correction, the systems were successfully brought back into production and reintegrated into our infrastructure. All components have been running stable since 06:30 UTC, and no further anomalies have been observed. We continue to monitor the platform closely, but no additional impact is expected. Thank you for your patience and cooperation throughout this incident.
