It is still a way to measure it, even if it's not that accurate.

I'd like to see a repeat but with a week timescale.  If you parse carefully, if all the $major sites are broken in the 
same way at the same time, it's easier to justify leaving it broken.  (eg: if Google, Yahoo and Bing all do IPv6 at 
once, neither has to worry about losing market share to the other due to misbehaving ipv6.  That's how I read igor's 
email about the 182k users, even if I still think we would be served with a longer test).

The most interesting data for me is looking at the sites that have 'majorly' broken IPv6 dns.  I count 600+ sites that 
are returning weird things like ::1 or ::ffff: addresses.  My favorites are the .gov site on the list and the city of 
albany.

Here's a pointer to the list:
