RESTON, Va. -- XO Communications today announced the completion of its 800 Gigabit (Gbps) capacity upgrade on major coast-to-coast routes of its nationwide fiber optic network and the unveiling of a new, groundbreaking installation guarantee for wholesale customers that need faster provisioning of high-capacity network services.

As a result of the explosion in customer driven demand for bandwidth-intensive Web 2.0 applications and services including online video streaming, rich multi-media content, wireless data, HD video, and higher-speed broadband offerings, service providers such as cable companies, content providers and wireless and wireline telecommunications companies are facing increased demands on their networks for more capacity. Despite this demand for increased network capacity, many wholesale customers face prolonged provisioning delays with their current network services provider.

XO "10 Gigs in 10 Days" Guarantee

To help wholesale customers obtain high-capacity network services more quickly, XO Communications is offering the XO "10 Gigs in 10 Days" Guarantee. This groundbreaking, industry-first installation guarantee offers wholesale customers the ability to order 2.5 Gbps or 10 Gbps high capacity network transport services and have them provisioned in 10 business days across select major coast-to-coast routes on the XO network. Under guarantee, if XO Communications fails to install the service within business 10 days, the customer will be eligible for a one month service credit for each year of the customer's contract. The "XO 10 Gigs in 10 Days" Guarantee is being offered from November 1, 2007 until December 31, 2007 to wholesale customers that sign two- or three-year contract terms.

"This guarantee is a demonstration of the power of the XO network and further differentiates the capabilities and value XO can offer customers," said Ernie Ortega, president of XO Carrier Services. "Our continuing investments to expand the capabilities of our network in terms of capacity and industry-leading optical technology have enabled us to respond quickly to customer demand and become the new, more agile provider of long haul and high- capacity network services."
