One or more techniques and/or systems are disclosed for providing awareness of user availability. A user may activate a device, and a request to manage an availability status can be sent from the device to a communication service. The communication service may resultantly set up monitoring of the user status, and the availability status of the user can be set to available. If an active status update is not received from the user device, the availability status of the user can be changed from available to away. If an active status update for the user continues not to be received (e.g., for a few hours) and/or device connectivity seems lost, the availability status of the user can be changed from away to offline. This can be done in a resource/power efficient manner by not requiring continual execution of an associated application and/or continual network connectivity of the device.
