Superinsulators discovered. What is it actually?

Scientists claim that they discovered a superinsulating state of matter. What is it actually?

https://arxiv.org/pdf/1209.0530.pdf

Does it imply an infinite dielectric strength, an infinite dielectric permittivity or neither?

I suggest its insulating properties still can't be literally infinite, what are more realistic limits of that stuff?

Apparently it isn't known if permittivity is infinite or not: https://en.m.wikipedia.org/wiki/Superinsulator

No, it is not infinite just much lower than normal matter even superconductors do not actually have zero resistance, it is just EXTREMELY small. You can test this by running a AC current instead of DC current into a superconductor.
