Correct. If you have IPv6 _properly_ disabled in the OS. Such that
applications attempting to open IPv6 sockets for use get denied. Squid
3.1.10+ will pick that up next restart and not try to perform IPv6 again
until next restart.

There is the small matter of a lot of garbage tutorials about how to
disable IPv6 in the OS though. It has to be done in a way where a
program opening a IPv6 socket gets an error message back.
  Not letting the app open and use the socket, (spewing errors out all
over the place) or to hanging (frowning mostly at some RHEL user blogs
there).

Re-building Squid with --disable-ipv6 is another more extreme option.

I recommend this way.
  * Site-specific to allow access to all the working v6-only sites (1%
of the Internet now).
  * Easily reversible once the site starts working.

Best best way is to get the site fixed ASAP. From the other post by Rick
from Carfax it looks like they are on the issue now.
