iCloud: offline
This article has been archived and is no longer updated by Apple.
An iOS device is offline if it’s turned off or not connected to a data network, such as EDGE, 3G, 4G, or Wi-Fi. A Mac computer is offline if it’s turned off or not connected to the Internet via Wi-Fi or Ethernet.
If a device is offline (or if Find My iPhone is trying to connect to the device), a gray dot 
appears beside the device in the My Devices list.
