A failover system can receive active data from user devices running an application specific to a service entity providing an application service. For each user device, the active data can indicate a current status. The failover system can transmit restoration data to the user devices for storage to restore the current status of the user devices in the case of a failover event. When a failover event occurs, the failover system can recover the restoration data from a first user device to restore the current status of the application service for the first user device.
