NTT Com's Japan - U.S. Backbone Bandwidth Reaches 400 Gbps

TOKYO, January 13, 2011 - NTT Communications Corporation (NTT Com) announced on January 13 that it
has expanded the data-transmission capacity of its Global IP Network between
the United States and Japan to an industry-leading 400 gigabits per second
(Gbps). The new capacity, equivalent to approximately 24,000 channels of
digital terrestrial television or about 3.5 centuries' worth of content in a
daily newspaper, further enhances the company's leadership in Tier-1
transpacific IP connectivity.

NTT Com's global IP backbones are connected to fixed and mobile telecom
companies, Internet service providers (ISPs), data center operators and
content providers, enabling customers to meet their growing needs for
Internet capacity coupled with high-quality service. NTT Com has expanded
bandwidth sevenfold compared to just five years ago, responding quickly to
new demand created by the spread of broadband networks and the growing
popularity of online video, music, social networking and micro-blogging. The
current jump from 300 Gbps to 400 Gbps was achieved in less than one year.

NTT Com launched the precursor of its current Global IP Network Service
with a 45 megabits per second (Mbps) service in 1997. U.S. - Japan bandwidth
was dramatically increased to 1 Gbps when the company acquired Verio and its
Tier-1 IP backbone in 2000. NTT Com became the first network provider to
measure network-latency variability with a jitter-type service level
agreement (SLA) in 2005. The reliability of the NTT Com Global IP Network was
capably demonstrated in December 2006, when network traffic was rerouted with
minimal delay following a destructive undersea earthquake off Taiwan. In
2008, the company introduced a traffic-analysis system that monitors network
traffic to detect and report traffic anomalies to IP network operators.

NTT Com looks forward to continually enhancing its Global IP Network for
high-quality, high-capacity data transmission services offered 24/7 globally.
