What can be inferred if FortiGate contacted one server for FortiGuard communication?

When FortiGate contacts one server for FortiGuard communication, it implies that the default communication settings are being utilized. By default, FortiGate devices are configured to communicate with FortiGuard servers using predefined settings that typically direct them to a primary server for updates and services.

If the FortiGate device is only making contact with a single server, this suggests that it has not been configured to take advantage of multiple FortiGuard servers, which might be present to ensure redundancy and improved reliability. In typical deployments, having multiple servers for redundancy would allow FortiGate to route traffic as necessary, especially if one server were unreachable; however, contacting just one server indicates that the optimal configuration for redundancy might not be in place.

This understanding can be essential when troubleshooting potential issues with FortiGuard communications or when trying to enhance the resilience of the network by considering alternative configurations.
