sounds bizarre that windows is assuming that protocol stability operates on
a 30 day basis.  What if ipv6 is tweaked up on day 1, then ipv6 goes down
on day 2 because the corporate lan IT people doesn't know and doesn't care
about ipv6, and the W8 end users find themselves experiencing 29 days of
irritating timeouts?

I'm sure that the Microsoft people have thought about this, but the blog
posting doesn't give enough details.
