CloudFlare 特地寫了一篇討拍文在分析對六個 ISP 的超高成本:「Bandwidth Costs Around the World」。
其他的就不講了,先看對價錢的定義:
As a benchmark, let's assume the cost of transit in Europe and North America is 10 units (per Mbps).
然後來看亞洲區以及 HiNet 的部份寫了什麼:

Two Asian locations stand out as being especially expensive: Seoul and Taipei. In these markets, with powerful incumbents (Korea Telecom and HiNet), transit costs 15x as much as in Europe or North America, or 150 units.
成本大約是 15 倍。另外說明這六個 ISP 佔了他們 50% 的頻寬成本 (以及 6% 的流量):
Today, however, there are six expensive networks (HiNet, Korea Telecom, Optus, Telecom Argentina, Telefonica, Telstra) that are more than an order of magnitude more expensive than other bandwidth providers around the globe and refuse to discuss local peering relationships. To give you a sense, these six networks represent less than 6% of the traffic but nearly 50% of our bandwidth costs.
為什麼有種濃濃的既視感 XDDD
最有趣的是底下那六個連結 ... CloudFlare 在鼓吹使用者去跟 ISP 反應 peering 的問題 XD
Ask HiNet to peer with CloudFlare in Taipei
