Cubbit Cells are designed to be always on. You are not supposed to either unplug your Cubbit Cell or unplug any physical storage you have attached to the Cubbit Cell. If you do, you will be notified about the issue and asked to solve it within a period of time in order to maintain your storage space in the Swarm and contribute to a more reliable and stable network for everyone. If you are having issues getting your Cell back online our technical support team is always available to help!
