The April 2013 rankings include version 2 of the volume compilation method, with precise counts, resulting in slightly different ranking orders.
For example, OVH, Hanaro, and Strato are the top three in both
v1 and
v2,
but in a different order,
in the
April 2013
worldwide from CBL data.
Initially, we are only pubishing v2 for March and April 2013. In a few weeks we will publish the rest of the historical v2 rankings back to match the same months as the v1 rankings. Old v1 rankings will be kept online indefinitely for comparison, but all new rankings will be v2.
