Monitoring
The cause of the earlier service disruption was traced to a failure within the datacenter network infrastructure. Traffic was successfully redirected to a secondary network path while remediation efforts were carried out.
The affected network component has now been restored and the vast majority of services are operating normally again.
The datacenter engineering team continues to closely monitor the environment to ensure service stability, and we remain in contact with them while monitoring continues.
If you continue to experience any issues with your 3CX system, please contact our support team.
