This assumes cosmological principle applies to the Internet, but Internet
traffic is not uniformly distributed.

It is entirely possible, and even reasonable, that AMSIX ~5% and GOOG 40%
are bps shares, and both are correct. Because AMSIX sees large entropy
between A-B end-points, GOOG sees very low entropy, it being always the B.

Certain tier1 transit network could see traffic being >50% IPv6 between two
specific pops, so great IPv6 adoption? Except it was a single CDN sending
traffic from them to them, if you'd exclude that CDN flows between the pop,
the IPv6 traffic share was low single digit percentage.

I am not saying IPv6 traffic is not increasing, I am saying that we are not
doing any favours to anyone, pretending we are on-track and that this will
happen, and that there are organic drivers which will ensure we are going
to end up with IPV6-only Internet.
