The central question addressed in this paper is whether a content delivery network (CDN)needs to deploy its servers in a large number of locations to achieve its current levels of performance.Our study indicates that a relatively small number of consolidated data centers might provide similar performance to end-users. or over 30%of the total 34,000 servers claimed by Akamai during the study period,were pingable.
