As I said "default on" is the problem.  If it was manually turned
on then the issue wouldn't exist and people tend to test things
when they turn them on.

World IPv6 Day will flush out some of these routers.

Additionally its the applications themselves that are broken.  You
don't have to wait 1/2 a minute before you try the next address.

People complain about both directions.  IPv4 mostly ISP's can fix
one direction (there shouldn't be a ISP that can't get upstream
IPv6 working today) and content providers can fix the other.
