ZURICH, Switzerland--(BUSINESS WIRE)--March 22, 2000

Carrier1 International S.A. (Neur Markt: CJN; NASDAQ: CONE), the Pan European facilities-based provider of end-to-end Internet, bandwidth, data center and access solutions, announces today the construction of its 32 km high-fiber-count Paris metropolitan network. When completed in August of this year, it will interconnect major tele-houses, carrier hotels, and telecoms access points in Paris and will cost less than $5 million.

This new network will enable Carrier1 to cut local tail costs and significantly improve customer-provisioning time. It closely follows commencement of the 120-km city ring now under construction in Amsterdam which is scheduled for completion this summer.

This contract meets the need for high-speed applications which continue to explode in Europe. Fiber connectivity to the major data and media centres will be a key source of competitive advantage for Carrier1. The capital-efficient approach that Carrier1 has already demonstrated in its long-haul network will continue to be replicated in metropolitan area network builds as Carrier1 takes advantage of pre-sales, joint builds and fiber/duct swaps. "Such city rings enable us to deliver our broad range of services to our customers in a much more efficient manner," said Neil Craven, Vice President of Business Development at Carrier1.

Carrier1 is on track to complete 20 such city rings by the end of 2001. These networks will connect major telecom centers as well as IT Mega-Centres being developed through its HubCo joint venture.
