I've been noticing that on a few servers.  If you hover over the yellow spots, 
you'll notice that the failures are always for different zones.  This tells me 
that it is more likely a timeout problem.  Testing is done with 'dig', and each 
test times out after 10 seconds, but retries 3 times to get an answer.  This 
should be plenty of time if the server is responding reliably.  Since the 
problem is only on the IPv6 side, it could indicate that your server host does 
not provide a very good IPv6 connection.

I'm sorry I don't have any simple answers to this problem.  Obviously the server 
itself is responding well, as seen in the status for ns6.fr, but it bogs down 
when sent a lot of queries on IPv6.
