Level 3 Completes Internet2 Optical Network Implementation 

New Nationwide Network Delivers 100 Gigabits per Second with Ability to
Expand

BROOMFIELD, Colo., June 20, 2007 - Level 3 Communications' Business Markets
Group today announced that the Internet2 nationwide, dedicated network
services backbone is operational. This new 100 Gigabits per second (Gbps)
network delivers an immediate increase in bandwidth and the capability for
future scalability to enable emerging applications for the Internet2
research and education community. The network delivers the underlying
optical technology required for Internet2 to dynamically provision multiple
10 Gbps wavelengths. This milestone enables Internet2 to remain on schedule
to complete member migration from the existing network to this new backbone
by later this year.

"With more than 10 times the capacity of the current Internet2 backbone
network, this powerful new network unlocks significant technology
possibilities for our members," said Doug Van Houweling, Internet2 president
and chief executive officer. "Level 3's innovative and collaborative spirit
has helped keep this large and complex network project on track, even
delivering the network ahead of schedule. With this latest major milestone
in our network deployment, Internet2 will continue to focus our efforts on
providing a smooth and seamless transition from the current network onto the
new platform."

The new Internet2 network is designed to provide point-to-point dedicated
circuits and IP services that can support next-generation applications in
critical fields like telemedicine, radio astronomy, distance-learning and
energy sciences research. The network will also serve as a platform for
network researchers to develop new networking ideas and protocols. Created
to enable a wide variety of bandwidth-intensive applications currently in
use and under development at campuses and research labs, the network is
designed to support growth and changes in Internet2 member requirements over
time. 

Under the terms of the multi-year agreement announced in June of 2006, Level
3 is providing dedicated backbone facilities comprising 13,500 long-haul
route miles, multiple customer colocation suites and newly deployed metro
fiber. Under the agreement, Level 3 is also providing wavelength and
high-speed IP services to Internet2 with options for private line, metro and
long-haul dark fiber services to interconnect the backbone with academic
institutions. 

"We are very pleased to have completed the delivery of a network of this
scale for Internet2," said Randy Dunbar, senior vice president of offer
management for Level 3's Business Markets Group. "We are proud to be an
Internet2 business partner and to be providing a network that delivers
increased bandwidth and scalability, enabling research and education
communities to capitalize on technology innovations."
