Computation of Adjusted Geographic Redundancy Index

Geographic Redundancy Index (GRI) allow to understand how different actual distribution of data centers from the uniform distribution within a single country. Across the countries number of locations, total number of data centers and number of data centers at each location. GRI itself may be not suitable measurement to compare situation in different countries. Therefore, Adjusted GRI has been designed. Adjusted GRI is computed as multiplication of GRI value for a given country and referenced value of DCnum (formula (2.5)): GRIAdjusted = DCnumreferenced * GRI
