I dont know to what capacity twitter uses cloudflare but cloudflare is rather ubiquitous. Even if twitter didn’t have services with cloudflare, when a user’s device resolves the domain name “twitter.com” to an IP address, it might go through Cloudflare’s DNS servers. And givien the ubiquity of Cloudflare DNS, this is likely frequently. By monitoring the DNS queries for Twitter.com, Cloudflare can estimate the traffic volume by analyzing the number and frequency of requests received.

I don’t know why cloudflare’s CEO would do that or where he keeps his huge steel balls, but today I learned I can mine Cloudflare’s internet usage data. And I might have found a new hobby!

Cloudflare Radar has an API that gives access to Cloudflare’s data on global Internet traffic..

Radar’s API is free, allowing academics, data sleuths and other web enthusiasts to investigate Internet usage across the globe.
