看到「South Korea fines Facebook $369K for slowing user internet connections」這則新聞，裡面提到 Facebook 的 reroute 行為：
The Korea Communications Commission (KCC) began investigating Facebook last May and found that the company had illegally limited user access, as reported by ABC News. Local South Korean laws prohibit internet services from rerouting users’ connections to networks in Hong Kong and US instead of local ISPs without notifying those users. In a few cases, such rerouting slowed down users’ connections by as much as 4.5 times.
沒有告知使用者就導去香港或是美國的伺服器，聽起來像是 GeoDNS 的架構，以及 Facebook 的 CDN 架構幹的事情？不過在原報導裡面，另外一個指控是：
The KCC probed claims that Facebook intentionally slowed access while it negotiated network usage fees with internet service providers.
