Juniper does have very high code quality for IPv6. In fact we haven't
experienced any operational problem with running it in parallel to
IPv4, in contrast to The Router Vendor on dedicated routers.

Non-availability of high-quality IPv6 connectivity in US is not a good
reason to mess up European and Asian progress in this area.

You are really implying that today's user community has similar
requirements to that at those times?

Today you cannot tell the users "use IPv6, and by the way, don't worry
if you don't have connectivity, it will propably come back in a couple
of days".
