    RFO 14.07.21

    On 14.07.21 at 10:14 we became aware of an issue at one of our data centres where one of the links started flapping at an extremely fast rate causing our platform to experience an outage. Due to speed of the flapping, the automatic failover was not able to kick in and so the link had to be disabled manually. The consequence of this put an excess load on our servers and database clusters, preventing new calls to be made and ongoing calls to be terminated plus phones to deregister. The re-registration process caused the available port capacity for registration to be exhausted. We have now further increased capacity and improved the monitoring of the cluster going forward.
