Content displayed on your monitors is downloaded and played locally. In an event of Internet outage, Yodeck-enabled monitors will continue to work fine, at least for 15 days or up to a full month. But you will not be able to change what gets displayed until Internet access is back.
If the Internet outage is prolonged, then monitors will black out and display a discreet informative message.
