Node usage statistics

The following is a list of PCP nodes in order of "popularity": the ones consulted most often at the top. The first number after the file name gives the absolute number of consultations for a 3.5 month period, the second number gives the percentage of the total number of nodes consulted during that period. The list has been cut off so that only nodes consulted at least 10 times appear.

The next section gives the countries or domains ordered according to the percentage of consultation done by computers belonging to that domain. More detailed statistics (including all nodes and hostnames) can be found here.
