Over the past few days I have been using tools to examine DNS and CNAME records for a lot of the major sites on the web, to see which CDNs are delivering their content. While there have not been a lot of surprises, I did find out that Level 3 (LVLT) is delivering videos for Netflix (NFLX) and the NFL and delivering small objects for CNN.
I have been saying for some time now that Level 3 is getting some good traction with its CDN offering, yet many ask me if that is the case, why hasn’t Level 3 announced a lot of these big customers? While the company has announced a few, like the NHL, in many cases customers don’t let CDNs use their name for press or marketing outreach. This is quite common amongst all CDN customers and not unique to Level 3.
But by using tools that examine DNS and CNAME records, it’s not too hard to figure out which CDNs are delivering the content. That’s exactly what I found out when I examined where content from Netflix and CNN is coming from. While it was always clear that Limelight (LLNW) delivers the vast majority of Netflix’s content, Level 3 is also delivering some of its videos and Netflix’s business is not exclusive to Limelight as I originally thought. And while Akamai (AKAM) is still delivering all of the videos that I saw coming from CNN.com, many of the small objects on CNN.com are being delivered by Level 3′s caching network.
