虽然对宽带基础设施的大量投资提高了许多非洲国家的宽带速度，但用户最终获得的可靠性和性能也取决于网络和互联网服务提供商之间的互联以及内容、服务和应用程序的托管位置。通常，远程目的地的高延迟会带来严重的性能瓶颈，这表明除了在更高吞吐量链路上的投资外，还应致力于改善互联网服务提供商之间的互连，并将内容放置在离用户更近的地方。通过解开非洲内容获取、使用、托管和分发的复杂性，这项研究提供了三个主要贡献。首先，它通过在非洲地方新闻网站上开发一个案例，讨论了与非洲当地内容和服务的使用、托管、分发有关的挑战。其次，它为所有非洲国家的本地内容使用、托管和分发提供了公开的测量数据和指标。第三，它从内容的角度就如何改善互联网接入和使用以及基础设施性能提出了一些政策建议。
Although a considerable investment in broadband infrastructure has improved broadband speeds across many African countries, the reliability and performance that users ultimately receive is determined also by the interconnection between networks and Internet Service Providers (ISPs) and by where the content, services and applications are hosted. Often, high latencies to remote destinations introduce significant performance bottlenecks, suggesting that, in addition to investments in higher throughput links, effort should be devoted to improving interconnection between ISPs and locating content closer to the users. By untangling the complexity of content access, use, hosting and distribution in Africa, this study offers three main contributions. First, it discusses challenges related to usage, hosting, distribution of local content and services in Africa, by developing a case on African local news websites. Second, it makes publicly available measurement data and indicators for local content use, hosting, and distribution across all African countries. And third, it provides points of policy recommendations on how to improve internet access and use, and infrastructure performance from a content perspective.
