That's because the 'v6 network' is broken enough that putting
AAAA records on sites that need to be well reachable is a bad idea.
Given the above, I think there is no myth.. !
For example, due mainly to Vista's 6to4 tunnelling stuff (based
on researching a random sample of users), I'd lose about 4% of
visitors to my web-sites if I were to turn on AAAA records.
Has anyone who was using AAAA records for a site turned them off
Yes. We tried it on one of our client's rather high profile sites
and had to turn it off because of exactly that problem.
Ditto, we started enabling v6 a few years ago and tried dual stacking
some servers including DNS and www .. we noticed that hosts were
doing DNS lookups over v4 that would yield AAAA results to v6
addresses they could not reach and they preferred AAAA over A so the
end user experienced a mysterious hang then a timeout error
