LONDON, May 7 /PRNewswire/ --

- Twitter Selects NTT America Hosting Platform for Performance and Growth

Twitter, a leading provider of social messaging services, and NTT
America, Inc. (NTTA), a wholly-owned U.S. subsidiary of NTT Communications
Corporation and a global enterprise solution provider that integrates
networks, hosting and Web infrastructure services, today announced that NTTA
is providing managed IT infrastructure services for Twitter, Inc.

The integrated NTTA solution includes fully managed hosting, managed
security, managed networking, and a tier one global backbone. NTTA's SAS 70
Type II audited Premier Data Centres provide an IT
infrastructure-as-a-service that is fully redundant with high availability
and scalability to support Twitter's continued rapid growth. Additionally,
NTTA Professional Services bring a proven technical team to the solution to
manage IT infrastructure issues, thus enabling Twitter's IT staff to focus
priorities elsewhere.

"NTT Communications' history of reliability and its global perspective
were key factors in our decision to select NTTA as our hosting services
provider," said Twitter co-founder Biz Stone. "As Twitter grows and more
people around the world depend on our infrastructure, we feel an increased
responsibility to make the right decisions for the people who have helped
make us a success as well as those who have yet to discover our service."

Lee Mighdoll, Twitter Vice President of Engineering and Operation, noted,
"With NTTA, we can focus our resources on developing software and serving our
valued user community rather than on building, financing, and managing an
in-house IT infrastructure team."

"We are proud that Twitter selected NTTA as its trusted growth partner,"
said Don Goodwin, Vice President of Sales and Marketing. "NTTA IT
infrastructure-as-a-service enables Web 2.0 companies and their investors to
maintain a laser focus on their strategy, get to market faster and preserve
capital. It also significantly reduces the cost and energy required to build
and maintain an IT infrastructure. By deploying the NTTA Enterprise Hosting
Platform, Twitter can easily scale its application to deliver on its promise
of reliability to its user community around the world."
