Re: per month per Mbps to 28 euro cents
People think that the public IXPs are important but the majority of most large ISP's traffic doesn't pass through IXPs. Most traffic is routed through private peering to people like Google, YouTube, Netflix and the CDN providers. Sure BT has 350GB of LINX peering, but I can bet that their total traffic volume is much higher than that.
This is also why I find the Netflix rant strange, they only have 80GB of LINX peering because most of their connectivity is private peering and the rest of Netflix content is delivered by on-net appliances within the ISPs themselves (providing 100's of GB of capacity).
