ATLANTA, GA – (March 20, 2008) – Internap Network Services Corporation (NASDAQ: INAP), a global provider of end-to-end Internet business solutions, announced today that ibox TV, a pioneer in interactive entertainment, has selected Internap’s content delivery network (CDN) to stream Spanish-language television to online audiences worldwide.

ibox TV, which launched in 2006 as Movisat Networks, began as an online, pay-per-view station streaming the 2006 FIFA World Cup – one of the most watched sporting events in recent history. Today, ibox TV offers free programming including news reports, music videos and access to artistic events through the company’s Web site at http://www.myiboxtv.com. Based in Miami, Florida, ibox TV’s market has grown to more than a million visitors per day. In addition to television programming, the ibox TV Web site provides viewers with chat capabilities, a virtual store and the ability to upload video to the site. In order to ensure successful content delivery, ibox TV chose Internap’s Managed Server and Streaming Services for Windows Media.

“Internap has been our IT platform and solutions partner enabling ibox TV to reliably deliver live programming over the Web to millions of Spanish-speakers around the world,” said Fabian Esteban, president and chief executive officer of ibox TV. “Internap’s CDN and Managed Server, along with its exceptional engineering expertise and customer support, have played a pivotal role in our success and is the primary reason we’ve become such a highly viewed channel.”

Internap’s global 100 percent Service Level Agreement (SLA) supported content delivery network (CDN), and its fully scalable Managed Server, enables ibox TV audiences to receive the same high-quality viewing experience 24/7 regardless of their geographic location.
