Do you resend events if there are any cloud-to-cloud integration issues?

The Data Connectors will queue up events if the URL it is pointing to is not acknowledging them. It will then try to resend them with an incremental backoff timeout.

There's no sensor data buffered in the Cloud Connector or the sensor. The sensor needs to be within range of a Cloud Connector, that is connected to Disruptive's cloud, for data to be saved and available via Studio and the API.
