How is a superinsulator defined? Is it just zero conductance at finite temperature?

In addition, I think there needs to evidence of a stiffness to number fluctuations, just as stiffness to phase fluctuations (Meissner effect) is essential for establishing superconductivity. Not sure what the best measurable signature is.
