Every few weeks, I’ll run trace routes on a particular group of websites, to find out what CDNs are being used. I ran trace routes on the Alexa sites that are ranked #25 through #61, and based in the US. The 25th most visited site is imgur.com, #26 is weather.com, and so on. The full results for the trace routes are in the CDN Stats page.
Below is a summary. I skipped bank sites and adult sites. Akamai came in first place by a large margin. Keep in mind that most high volume websites sometimes use two or more CDNs for delivery. When a CDN delivers the main domain like www.imgur.com, we call this full site acceleration.
Summary of Trace Routes (Alexa Sites from #25 – #61)
- Akamai – 23 websites
- CloudFlare – 2 website
- EdgeCast – 1 website
- Amazon – 1 website
