It’s an issue I’ve been reporting on for weeks to try to discover the reasons behind what appears to be an extreme drop on broadband throughput for select U.S. internet service providers during prime time. It’s an issue that is complicated and shrouded in secrecy, but as consumer complaints show, it’s becoming increasingly important to the way video is delivered over the internet.

The problem is peering, or how the networks owned and operated by your ISP connect with networks owned and operated by content providers such as Amazon or Netflix as well as transit providers and content deliver networks. Peering disputes have been occurring for years, but are getting more and more attention as the stakes in delivering online video are raised. The challenge for regulators and consumers is that the world of peering is very insular and understanding the deals that companies have worked out in the past or are trying to impose on the industry today is next to impossible.

It's difficult to understand this issue, but as the article says, it's increasingly important.
