Measuring the Internet is hard. Really hard. The scale and diversity of the system make obtaining objective, comprehensive measurements of any aspect of the interconnected whole virtually impossible. Instead we must rely on sampling and educated guesswork, with all of the caveats that entails. Nevertheless, in the firm belief that data are better than no data, we highlight a couple of pieces of interesting, recent work that provide some hard data to underpin discussion and speculation about how the Internet is changing.
