Edge caching is a common practice used by ISPs and application and content providers in order to improve the end user experience. Companies like Akamai, Limelight, and Amazon’s Cloudfront provide local caching services, and broadband providers typically utilize caching as part of what are known as content distribution networks (CDNs). Google and many other Internet companies also deploy servers of their own around the world.

By bringing YouTube videos and other content physically closer to end users, site operators can improve page load times for videos and Web pages. In addition, these solutions help broadband providers by minimizing the need to send traffic outside of their networks and reducing congestion on the Internet’s backbones. In fact, caching represents one type of innovative network practice encouraged by the open Internet.

Google has offered to “colocate” caching servers within broadband providers’ own facilities; this reduces the provider’s bandwidth costs since the same video wouldn’t have to be transmitted multiple times. We’ve always said that broadband providers can engage in activities like colocation and caching, so long as they do so on a non-discriminatory basis.

Despite the hyperbolic tone and confused claims in Monday’s Journal story, I want to be perfectly clear about one thing: Google remains strongly committed to the principle of net neutrality, and we will continue to work with policymakers in the years ahead to keep the Internet free and open.
