This *was* a troll, right...?

If service is critical enough to me that 20 second hiccups make
a difference, I'll find two providers to provide connectivity to the
location via relatively cheap waves, and I'll run link-node protection
at my layer to get fast reconvergence in the sub-second range.
And I'd warrant it'll still come out cheaper than the government-built
costs we see in Australia.

I really, really don't think more government intervention is the right
answer.
