Networked VGA Grid's Wowza Streaming Cloud integration is designed for maximum uptime. If a network or
power interruption Networked VGA Grid temporarily prevents the system from communicating with the
Wowza Streaming Cloud service, every attempt is made to reconnect after the power or network is restored.
Refer to the following chart for specific details of what to expect when there is a network or power failure. Note
that Wowza Streaming Cloud stops a live stream if it fails to receive data (i.e. idle stream) for a period loger than
your configured Idle Timeout. You can configure the Idle Timeout value is specified in the Transcoder setup
section of Wowza Streaming Cloud.
