Interliant Service Enables Leading Application Development and

Services Company to Concentrate on High End Application Development

Interliant, Inc. (Nasdaq:INIT), a leading global application service provider (ASP), announced today that AguirreIS, a leading application development and service company, has selected the ASP's INIT Managed Messaging for Domino service to focus on building customized information system solutions for its clients without having to worry about managing the infrastructure. Interliant maintains multiple AguirreIS Domino dedicated servers in one of its state-of-the-art data centers, ensuring an application environment with the highest levels of service, security and reliability.

AguirreIS has been building practical, cost efficient, secure, real-world Web-based solutions and information systems for nearly 20 years. During this time, AguirreIS has provided customized solutions to clients in over 35 states and 30 countries. The company works with a diverse range of organizations from both the public and private sector.

Interliant's INIT Managed Messaging for Domino service allows AguirreIS to focus on strategic work - developing customized applications - instead of supporting servers and application infrastructure. As AguirreIS builds applications for its clients, the company leverages Interliant's seven years of experience in managing Domino severs to ensure that a reliable, secure infrastructure is in place. Interliant provides AguirreIS with a broad range of services, including: Domino infrastructure design, installation and configuration of Domino servers, 24x7 remote monitoring and management of the servers, security (firewall and intrusion detection), backup, fail-over, and disaster recovery, and hardware and software fulfillment.

"AguirreIS builds applications that will help our clients become more effective, productive, and ultimately more successful," said Shawn Coyle, MIS Director for AguirreIS. "We simply do not have the bandwidth to worry about managing the infrastructure on a day-to-day basis. We selected Interliant for multiple reasons, including their years of experience in supporting Lotus Domino infrastructure for customers, they own their own data centers, and they truly understand our business. We look forward to a long-term relationship with Interliant."

"There are two components that must always be addressed when developing information technology solutions - the first is building applications, and the second is managing the infrastructure to support the applications," said Patty Jacobson, vice president of INIT Managed Messaging for Interliant. "Interliant's INIT Managed Messaging for Domino service provides AguirreIS with a reliable messaging and collaboration application infrastructure to support their customized applications in order to meet the demanding needs of its clients."
