Alexa traffic reports broken?!

Is Alexa broken? I’ve noticed that all the major blogs had their ranking cut in half over the past week or two. It’s as if 5-20,000 sites were removed from the Alexa index.

Our blogs have been growing, but looking at Kotaku’s traffic log and our traffic logs it is clear that neither site grew to the point at which they would have a 10-40,000 boost.

Perhaps Alexa took out the Asian blogs that were quickly filling up the top of the index? The 100M+ Chinese users online now don’t have too many sites to look at. As a result they have pushed thousands of Chinese sites into the top of the Alexa rankings over the past year. Maybe Alexa is making another index for them? I’ve also heard that a lot of people in Asia use the Alexa toolbar, and that the Alexa data has become meaningless because of this.

Can someone from Alexa add some transparency to the index as it is really confusing people!
