Data center operator Interxion Holding (INXN) has been acquired by U.K.-based Telecity Group in a $2.2 bil deal. More data consolidation could be on the way, and analysts say the rival-eliminating merger bodes well for Equinix (EQIX), whose shares edged up 0.6% to 221.07. Last month telecom network operator Zayo Group (ZAYO) said it would buy Latisys for $675 mil. Interxion shares leapt 13.6% to 31.80.
