Google says >30% of USA usage is over IPv6. https://www.google.com/intl/en/ipv6/statistics.html#tab=per-... Akamai says 40%. https://www.akamai.com/uk/en/about/our-thinking/state-of-the... But it shows a huge jump in May last year, not sure what that's about.

Most countries have a small number of dominant telecom providers. When they adopt IPv6, you'd normally see a very big jump in a short amount of time.

Sure, but that doesn't explain why they show the USA jumping from 27.7% to 38.7% in one day (5/24 to 5/25) when Google's numbers don't show a similar rise.

You see the same jump at the same time in some other countries, such as Norway and Canada. I would guess that's down to a measurement adjustment on the part of Akamai, enabling them to see more adoption that they had been missing.
