In CDN news this past weekend, a judge has overturned the jury verdict in the Akamai vs. Limelight patent infringement case. Akamai has said it intends to appeal.
The judge cited Muniauction v. Thomson Corp. as the precedent for a judgement of law, which basically says that if you have a method claim in a patent [...]

Matthew Sacks has blogged Keynote performance test results for Akamai via Distribution Cloud.
There are other Akamai resellers out there, but Distribution Cloud posts its prices publicly, starting at 50 GB for $150 per month ($3/GB), and going up to 1 TB for $2,200/month ($2.20/GB), with storage at $15/GB. That’s 10x the cost of Limelight [...]

It is possible that I am going to turn out to be mildly wrong about something. I predicted that neither Amazon’s CloudFront CDN nor the comparable Rackspace/Limelight offering (Mosso Cloud Files) would really impact the mainstream CDN market.

This post is the third in a series examining the Microsoft CDN study. My first post examined what was measured, and the second post looked at the blind spots created by the vantage-point discovery method they used. This time, I want to look at the availability and maintenance claims made by the study.
CDNs are inherently [...]

This post is the second in a series examining the Microsoft CDN study comparing Akamai and Limelight. The first post discusses measurement: what the study does and doesn’t look at. Now, I want to build on that foundation to explain what the study misses.
In the meantime, Akamai has responded publicly. One of the points raised [...]

Cheng Huang et.al.’s Microsoft Research and NYU collaboration on a study entitled Measuring and Evaluating Large-Scale CDNs is worth a closer look. This is the first of what I expect will be a series of posts that aims to explain what was studied and what it means.
The study charts the Akamai and Limelight CDNs, and [...]
