What problem is it causing you exactly? Squid getting a SERVFAIL means
it goes on and uses the IPv4 addresses instead.
It takes around 2-4 seconds to time out which can make access to the
site very sluggish.
NP: It is worth noting that this SERVFAIL happens on *less* IPv6-enabled
sites overall than on IPv4-enabled ones. About 0.01% of IPv6 sites last
time it was measured by APNIC researchers, and things have been steadily
improving. Disabling access to IPv6 networks *entirely* for all your
customers is a bit of overkill for that type of error rate.
I know, I'm trying to keep it enabled but people are complaining about
access to this site and what else am I supposed to do?
There has been a proposal with patch submitted in the last few days that
can be used to avoid this problem on an dst-IP specific basis:
