WorldCom Accelerates Rollout of Global Data Center Expansion in Europe

WorldCom to add 13 Data Centers across Europe for a total of 41 in 11 European countries

LONDON - May 31, 2000 - As part of its worldwide expansion in
global data centers, WorldCom today announced rollout plans for 13 new
International Data Centers (IDCs) across Europe over the next 12
months. These new IDCs will provide customers around the world with
highly secure, state-of-the-art, carrier-grade facilities connected
directly to WorldCom's broadband and IP networks in major European
metropolitan centers and complements WorldCom's recently announced
sweeping initiative to extend network, access and Web hosting services
to facilitate e-business around the world.

Building on its recent announcement to build 13 major colocation
centers in the U.S., WorldCom is on track to triple colocation space in
Europe and expand network colocation and Internet colocation space
worldwide to more than 280,000 square meters (3 million square feet) by
the first quarter of 2001. Six new centers, in Amsterdam, Dublin,
Luxembourg, Milan, Paris, and Stockholm, will make available 100,000
square meters (1.2 million square feet) in more than 34 locations in
Europe by the end of this year. WorldCom also plans to build
International Data Centers in seven additional key European cities by
the third quarter of 2001.

"WorldCom was the first pan European carrier to offer network
colocation services across Europe. The centers announced today leverage
WorldCom's extensive experience in providing state-of-the-art
network and Internet colocation services with Europe's premier
broadband network," said Ronald Kleinveld, WorldCom IDC Managing
Director. "Our customers want consistency from their
communications provider. That's why WorldCom offers a truly global
product with standard features, support levels and procedures, combined
with local sales and operational staff."

"The addition of the new data centers to our core telecoms
offering is key to WorldCom's position as a leading facilitator of
the e-conomy and will enable the explosive growth of e-commerce in
Europe," said Liam Strong, CEO of WorldCom International.
"IDCs form a key part of our overall strategy. As we continue to
build-out our network and access, the exponential growth in demand for
colocation space requires the ability to offer network and Internet
colocation services that provide greater access to the network. The IDC
program is the next logical step in that network evolution, opening up
the power and reach of the WorldCom global network to the new
generation of data and mobile services, allowing us to provision local,
pan-European and global services for a wide range of new and existing
customers."

Build-out of IDC capacity is a key facilitator for customers such as
Internet Service Providers (ISPs), Application Service Providers
(ASPs), corporate users and new carriers in both fixed line and
wireless technologies such as Digital Subscriber Line (xDSL), Wireless
Access Protocol (WAP) and Universal Mobile Telecommunications System
(UMTS).

WorldCom IDCs will offer highly secure, scalable broadband access to
the network, along with "best of breed" services in advanced
technologies.

WorldCom IDCs will offer global, end-to-end network and facilities
management on its own network. Internet access, a prerequisite for any
network deployment, will be provided through WorldCom's UUNET
global IP network and its industry-leading service level agreement.
WorldCom is also developing a complete range of hosting services for
the new IDCs.

In order to facilitate the best possible solutions for its
customers, WorldCom IDCs will also offer access to other carrier
networks, allowing customers to choose their network service provider
and ensuring that WorldCom IDCs consistently offer the full range and
scale of networking technologies.

WorldCom IDCs deliver industry-leading standards of service,
including 24/7 operation support, state-of-the-art power supply
protection, climate control, redundant connectivity and special
environment protection. Rack space is provided in a highly secure,
fully air conditioned environment with a range of access and network
connectivity options.
