An open source command line tool that gives you access to hundreds of servers around the world to run network utilities such as ping, traceroute, mtr and dig
I hope this will help developers and sys admins to quickly debug networking issues and run small benchmarks on their services. Without an API key it allows 10 tests per hour and 200 free tests for registered users. Just get a free account and copy your API key from the settings menu.
