This website is a collection of tools and resources for Cloudflare.
Cloudflare is a web infrastructure and website security company that provides content delivery network services, DDoS mitigation, Internet security, and distributed domain name server services. All of these tools are community run and maintained. There are no affiliations with Cloudflare.
The most useful tool is the test page. It will show you the information that Cloudflare knows (or, more precisely, assumes based on your IP and connection) about you. This includes your IP address, location, and other information. You can reach the test tool at test page.
The other pages are informational about the network (the POPs map, including past and present locations) and some FAQs.
You might be interested in the other website I run, available at here. It is the result of a project to understand the full scope of the Cloudflare network.
