Note you can have totally broken IPv6 connectivity and still be
fine on World IPv6 day.  You just need applications with good
multi-homing support.  No web site can check this for you.

If you are a application developer and want TCP example code that
will work well with a broken IPv6 connection have a look at my blog.
