Also, I welcome any developer to use our API to run any sort of network tests such as testing latencies (ping/http/dns), speed (http throughput), running traceroutes and figuring out how the internet is wired. Our background is in internet speed testing, we have been measuring internet connection quality since 2007 and helping millions of users each month with accurate speed testing tools. The API is free for non-commercial use, after few requests you will need to sign up for the free API key (this is to prevent abuse).
