As of October 2020, Chorus Limited, a wholesale infrastructure provider in New Zealand began offering a product called EdgeConnect allows ISPs to peer at the Auckland Internet Exchange from any local telephone exchange in the country. Standard prices are available for same district, same island, or different island connections.
In March of 2019, the Dutch regulator compelled Vodafone to publish its wholesale access rates or face a one million Euro fine.
The regulator in Botswana (BOCRA) published a rate card in 2014 and 2015 for access to the national fibre optic backbone. Granted this is a state-owned network which removes the complication of negotiating with the private sector but even if we just succeeded with state-owned networks, this would be a big leap forward.
In West Africa thanks to a directive in 2006 from UEMOA, the West African regional economic community established a practice of publishing backhaul and interconnection pricing.
