Too bad this was announced on 1st of April.

From the article: The only question that remained was when to launch the new service? This is the first consumer product Cloudflare has ever launched, so we wanted to reach a wider audience. At the same time, we're geeks at heart. 1.1.1.1 has 4 1s. So it seemed clear that 4/1 (April 1st) was the date we needed to launch it.
