first phase of a 21 MW expansion at the company's London Powergate facility. In August 2012, TelecityGroup acquired Tenue Oy, a provider of carrier-neutral data centres in Helsinki, Finland. In November 2012 TelecityGroup acquired Academica, a data centre and IT services operator, also active in Finland since 1996, giving the enlarged TelecityGroup Finland a total of three data centres and 2MW of operational capacity; 7MW of additional capacity will be opened in two new facilities in due course. In May 2013, TelecityGroup acquired SadeceHosting, a provider of data centre and hosted services in Istanbul, Turkey and in November 2013, TelecityGroup acquired 3DC, an independent data centre provider in Sofia, Bulgaria. In August 2014, Telecity’s founder Michael Tobin left the company following reported tensions with the board of directors. In February 2015, it was announced that Telecity would merge with Interxion, purchasing it in a $2.2 billion deal, thus creating a joint data-center operator, with a combined value of $4.5 billion. According to the two CEOs, a deal promised to deliver around $600 million in synergy savings. In May 2015, US data company Equinix announced it would be acquiring TelecityGroup for £2.35 billion ($3.6 billion), which would terminate Telecity’s deal with Interxion. Reuters reported that the acquisition of Telecity by Equinix would create the largest data center company in Europe. On 13 November 2015, the European Commission granted clearance for the Equinix offer to acquire Telecity. As part of this acquisition, the European Commission required divestment of eight of the datacentre sites on competition grounds, and these sites were sold to Digital Realty for $874 million. In January 2016, Equinix announced that it had completed the Telecity acquisition in a transaction valued at approximately $3.8 billion. The addition of Telecity data centers more than doubled Equinix's capacity in Europe, making the company the region's largest retail colocation provider.
