After experiencing some ArcGIS Online service issues, we have implemented a few service configuration changes and behaviour changes to improve the stability.

The change that may affect users is the visibility range of Nearmap imagery, which is set at 1:5,000,000. The initial zoom of the map depends on the application. If it happens to be smaller scale than 1:5,000,000, the users may not see anything, and will have to zoom in to be able to see the Nearmap imagery.
