NEW YORK, May 16, 2006 – AboveNet, Inc., a premier metro access provider of custom fiber solutions, today announced the launch of dcXchange, a data center to data center service delivering high performance connections over a dedicated DWDM core network, between prime locations in the Washington, D.C. & Northern Virginia market.  dcXchange is a pre-provisioned service delivering DWDM, SONET and Gig E connections for Enterprise, Carrier and Indirect Sales customers.  Supported by AboveNet’s Global Network Management Center, dcXchange offers simplicity and unsurpassed flexibility to support a broad range of applications for media and entertainment,  wireless backhaul, financial and banking industries as well as large bandwidth federal government requirements.
