Top 20 metros account for 71 percent of worldwide wholesale colocation revenue. North America accounts for eleven of the top 20 metros in wholesale colocation revenue.
Digital Realty is the leader in eight of the top 20 wholesale colocation market. Global Switch is the leader in three others in wholesale colocation markets. Other colocation operators that feature in the top 20 metros include 21Vianet, @Tokyo, China Telecom, CoreSite, CyrusOne, Interxion, KDDI, SingTel and QTS.
John Dinsdale, chief analyst at Synergy Research Group, said: “Hyperscale operators often focus their own large data center builds away from the major metros, in areas where real estate prices and operating costs are much lower, so they too will rely on colocation providers to help target clients in key metros.”
