Finding the CDN of any website is possible with a trace route. In most cases, the trace route can identify the CDN being used. It’s not 100% accurate but it’s good enough. Below are the trace routes for the Fortune 50. I decided to do a trace route on the main domain (www.hostname.com), in order to find out who is the leading CDN amongst those companies. I already knew who it was, but I was curious as to how dominant they were. It was just as I expected, Akamai dominates this segment.
Below are the results. Akamai came in first place with 27 of the 50. Level 3 came in 2nd place with 2 of the 50. Finally, CDNetworks and Amazon came in 3rd place with 1 of the Fortune 50. I did not do trace routes on the financial institutions for obvious reasons. Also, I was surprised by the number of Fortune 50 that did not have a CDN.
