It’s fibre from the home to your provider. New Zealand's current international connectivity is provided by three under-sea fibre optic cables with a combined total throughput of 73 terabits per second.
I merely told it to divide 73 terabits by the population of New Zealand and to express that in megabits. So yeah no consideration of usage patterns: "nonsense numbers" just like the supposed 46G wifi this story is about.
I do agree that all these numbers are pretty meaningless . Somehow truth in advertising laws don't apply to many of these claims. Only seen the Australian regulator really crack down on it.
