McLean, VA, April 12, 2016

(NYSE: GTT), the leading global cloud networking provider to multinational clients, announced today that it has expanded its relationship with Equinix, the global interconnection and data centre company, to provide direct network connectivity across three Equinix Cloud Exchange™ locations in Europe.
