Disconnection Recovery for XTreme Hubs

If there's a connection problem between the Windows XTreme Hub device and its Android devices, they will recover in the following ways.

Scenario Recovery Behavior
A device is currently downloading files from a Windows XTreme Hub device and receives a new set of download instructions from the deployment server. The device will cancel the current set of file transfers and start a new download process for the new instructions.
While downloading files, a device loses its connection to the Windows XTreme Hub device. At next device check in, the device will resume downloading from the point where the connection was lost. It will not restart the download from the beginning.
In environments with multiple Windows XTreme Hub devices, there may be rare occasions where some XTreme Hub devices have more recent files than others. If a device connects to a Windows XTreme Hub device with out of date files, it will download outdated files. However, as soon as it connects to an up to date Windows XTreme Hub device, it will update its files.
The Windows XTreme Hub device is offline (there is no connection between it and the deployment server) Devices will continue to try and connect to the Windows XTreme Hub device according to the settings specified in their advanced configuration.
Note: Even if all Windows XTreme Hubs are offline at the same time, devices will not fallback to the deployment server for distribution.

To force devices to use a deployment server for file distribution, you need to disable or unenroll all applicable Windows XTreme Hub devices. See Reverting to Deployment Server File Distribution for details.
