CloudFlare is provisioned by DNS. That means that, from the beginning, you've been able to turn CloudFlare on or off on a subdomain level. From the CloudFlare DNS Manager. Often, however, users have wanted finer-grained control.
Today, CloudFlare adds more than 250 customers every ~6 hours, but getting our first 250 took several months and a lot of faith. When we started working on CloudFlare, an employee at a major CDN company warned us that we had no idea all the crazy things people did with their websites.
We're happy to announce that CloudFlare's Miami data center is now online. Our 14th data center has been in the works for some time now. The new facility, which is among our largest, will serve much of Central and South America.
CloudFlare, as a service, illustrates the power of using DNS to make the Internet better. Unfortunately, some current legislation up for consideration in the United States illustrates the power of using DNS to make the Internet worse.
We regularly monitor the Alexa top 1 million websites for trends. Specifically, we've been tracking how many of them support IPv6 connections. The numbers are still low but have been improving.
