This next-generation connectivity platform is a combination

of best in breed enabling technologies and collaborations

with the leaders in content delivery and privacy solutions

Carrier1 International S.A. (Neuer Markt: CJN; NASDAQ: CONE), a leading European provider of end-to-end Internet, bandwidth, data center and access solutions, today announces the launch of its next- generation Internet delivery and connectivity platform.

The concept is centered on providing superior end-to-end connectivity on top of a state-of-the-art transport backbone. It combines core transport power with superior edge functionality. The service offering is based upon Carrier1's low-hop, thick Internet backbone infrastructure, combined with some of the world's leading providers of content, content delivery technologies and privacy solutions. Carrier1 looks to continually improve the delivery of content and technology-based functionality to the end user, and to reduce the bottlenecks associated with the advent of rich media and new mission critical e-applications.

Carrier1's next generation platform provides multifaceted solutions to enable enhanced connectivity:

Collaborations with leading Internet companies: Carrier1 has collaborated with some of the leading Internet companies to provide our ISPs with the best connectivity in Europe.

-- Content Connectivity: Carrier1 is hosting the equipment of the premiere
content delivery companies as they expand in Europe. Carrier1 is ensuring that
some of the most frequently accessed Internet content resides at the edge of
Carrier1's Internet network. As more of the North American Internet companies
focus on their market entry into Europe, they see the Carrier1 Co-Location
service being a key enabler for them to deliver quality services and
applications in Europe.

-- VISP Access: The Carrier1 Virtual Internet Service Provider platform
provides an access platform that ensures the end customer is directly connected
to the Carrier1 platform. This provides Carrier1 with true end to end control
of connectivity, which is crucial to achieve the highest Quality of Service. A
number of high-end streaming media companies are incorporating this aspect of
the platform into their business.

-- Content and Application Hosting: Carrier1's high-end hosting provides the
platform with the facilities to host both content and applications. A number of
mission critical B2B players are choosing Carrier1 for the complete platform
offering instead of traditional hosting.
