As Hive and HBD are blockchain assets, there's no need to worry if one of the access points is down - the assets are safely stored in Blockchain and nobody can steal them, unless they have your private keys. Generally speaking, blockchain assets are safer than your silver coins that can be stolen when somebody breaks in your home or the place you store them.
