Mashery Helps Companies with API Business Opportunities, Internap Supports Their Rapid Growth

ATLANTA, June 23, 2009 — Internap Network Services Corporation (NASDAQ: INAP), a global provider of end-to-end Internet business solutions, announced today that it is providing managed server hosting services for Mashery, a cloud-based API (Application Programming Interface) infrastructure management company.

Mashery helps customers to embrace a new distribution channel — one that lets them create thousands of new content partnerships and create an ecosystem out of which new user experiences and revenue opportunities can grow. Thousands of software-driven companies are releasing APIs in order to become Software as a Service (SaaS) providers, either as a primary or secondary line of business. Although every API is different, the infrastructure to manage them includes the same set of challenges for most providers. Adopting Mashery’s developer management and support services allows customers to focus on their core businesses rather than trying to manage the APIs themselves.

Internap’s broad product set, global network presence, and quality-of-service guarantees displaced the incumbent provider of managed server duties for Mashery’s Premium Service customers. The company will use Internap’s managed-server infrastructure as a backup solution for both standard and enterprise service customers.

“Despite, and perhaps driven by, a sluggish economy, Mashery has seen rapid growth. Best Buy, MTV, New York Times and Netflix are among a growing list of industry leaders relying on Mashery to manage their APIs,” said Oren Michels, Mashery Co-founder and CEO. “We chose Internap after an extensive business and technical vetting process. We found the company had the most robust set of MSP services combined with outstanding SLAs — both of which were prerequisites for Mashery and our premium-service customers.”

In 2008, Internap expanded its managed-server offering to a global footprint, which was also significant factor in the successful bid for the Mashery business.

“Internap has demonstrated its unique strength in meeting the requirements of companies like Mashery for 100 percent uptime in all aspects of their online business activities,” said Internap Vice President of Global Sales, Randal Thompson. “By relying on Internap to be the experts in managing servers and network connectivity, Mashery can keep the focus on expanding its core business of managing APIs for customers.”
