Global Capacity is a Waltham, Massachusetts-based provider of telecommunications Connectivity-as-a-Service including Carrier Ethernet, used by companies for Internet access and WAN connectivity.

[8] In November 2008, Global Capacity paid $15M to acquire Vanco Direct USA, a network service provider of consulting services for global corporate networks, and the owner of LATTIS (Local Area Transport Tariff Information System), an information tool for circuit pricing.

[16] In September 2014, Global Capacity announced its plan to buy MegaPath's wholesale and direct access business.

[18] In April 2015, the company announced the availability of MPLS VPN services over the One Marketplace platform, as a result of the network assets acquired from MegaPath.

The deal, anticipated to close in the third quarter of 2017, was expected to help GTT expand its SD-WAN and data center services.

One Marketplace allows network operators to obtain quotes on wholesale services, and it automates their purchases.

[22] Using the Covad legacy access infrastructure purchased from MegaPath, the company also sells its own Ethernet over copper and DSL connections to customers.

With Global Capacity's equipment located inside the phone companies' central offices (COs), One Marketplace calculates whether a customer can get Ethernet over copper service or DSL service at a specific address by measuring the distance from the customer site to the serving CO. As of January 2015, the One Marketplace platform included access to 41 points of presence (PoPs), 2,007 COs and over 4,500 last-mile network interconnections for customer service delivery.

[28] In 2011, the company received Internet Telephony Magazine's TEM award for their ability to help telecommunications expense management.
