TEMPE, Arizona, July 9 /PRNewswire/ --

- Fast-Growing PC Gaming Service Reduces Overhead and Improves
Its Customer Experience Through Tie-Up With Leading Content Delivery Network

Limelight Networks (Nasdaq: LLNW), a leading content delivery network
(CDN) for digital media, announced today that GameShadow, one of the rising
stars of the PC-gaming community, has selected Limelight as its exclusive
CDN. GameShadow chose Limelight because of its proven ability to scale to
accommodate large global audiences of gamers and to help build strong brand
loyalty by improving its customer experience when delivering content to its
rapidly growing customer base.

GameShadow fills an increasingly important and desirable niche in PC
gaming, providing a platform for gamers to download patches, demos, trailers
and other content. Since its intelligent client became free to download last
year, GameShadow's popularity has been booming with more than 750,000
registered users and the potential to reach millions worldwide.

The Oxfordshire, U.K.-based company was previously provisioning its own
servers but found the management overhead to be high and the experience for
users far from ideal. Under the new set-up, users are automatically connected
to Limelight Networks' globally-distributed network of thousands of servers,
dramatically improving download times.

"It's about reducing complexity in the way we deliver the files and
making sure we provide a great service level to our customers," said Tony
Treadwell, COO and Founder of GameShadow. "When growing the GameShadow
service, it became clear that we had a reputation to uphold and our original
file serving system was beginning to show strain under the load. We needed a
scalable and high-performing multi-access-point network that would allow all
of our customers worldwide to experience the best possible delivery speeds."

In addition to cutting the management overhead in half, Treadwell said he
believes the Limelight network provides a fully scalable and cost-effective
solution as the company grows to provide updates and patches to millions of
PC gamers. GameShadow can encourage this performance-sensitive group of
consumers to keep using the GameShadow service by providing a fast and
efficient user experience. "Limelight meets our need for a massive online
delivery network that has the capability and the scalability to support our
extremely large continuous and peak download requirements," he said.

"GameShadow provides one of the best gaming experiences for enthusiasts
worldwide," said George Meek, vice president, Europe at Limelight Networks.
"By choosing Limelight, they can now enjoy the benefits of leveraging the
most powerful CDN platform, providing their customers with 24/7 access to the
latest patches and updates for PC games."
