Lorenzo's reply to this statement

        Google isn't reachable. Â  There are no IPv6 servers for google.com.

was 

        Unfortunately, every time we've looked at the data, the
        conclusion has been that it would cause unwarranted user
        impact. IIRC the most recent blocker was a major US ISP
        whose clients would experience breakage if even just one
        NS record was dual-stacked. It's not an infrastructure
        problem: the servers have supported IPv6 for years, and
        some zones like google.fi do have IPv6 NS records.
