You can see Amazon Route 53 enabling IPv6 step wise between Oct 25
and Dec 22.  This was visible in the error graphs for EDNS Unknown
Version compliance.  You could see each of the 4 region being enabled
as individual steps in the graph.
<https://ednscomp.isc.org/compliance/ts/au.opt1fail.html>.

Now enabling IPv6 support is a good thing.  It would be nice however
to not be able to see it in error graphs.  The servers don't return
EDNS answers unless the EDNS version is 0.  edns1 and edns1opt tests
are not marked as "ok".  I don't know if it is a good thing or a bad
thing that so much of the Australian DNS is being served by AWS.
