You've written that the wrong way around. You've written the opposite of what Cloudflare writes.
They write that transit bandwith costs are similar in Europe and the USA, but Europe has more peering — it's around 50% of their traffic rather than 20%.
> The corollary is that in Europe transit is also cheap but peering is very easy, making the effective price of bandwidth in the region the lowest in the world.
Oops, yep, so I have. Should’ve read “much more widespread in Europe than the US”. Sorry, long day.
