In May 2015, Equinix said it would purchase the British company TelecityGroup, the largest acquisition in company history. The offer was cleared by the European Commission in November after Equinix agreed to sell eight of its data centers around Europe to Digital Realty Trust. In January 2016, Equinix completed the Telecity acquisition in a transaction valued at approximately $3.8 billion. The addition of these data centers more than doubled Equinix's capacity in Europe. In December 2015, the company purchased Japanese provider Bit-Isle, adding six data centers in Japan.
