30006: Layer's data source references a Web service
Your basemap layer contains a layer that references a Web service. Issues with network connectivity or load on a service may affect the performance of this layer negatively.
- Do nothing. You can accept the display difference as is.
- Alternatively, you can rebuild your map to use local data or reference a different Web service with better performance.
This message is simply telling you that a layer in your basemap layer references a Web service, and the layer could experience slower performance. You should evaluate the performance of the layer, as it may be affected by server load and network traffic.
