February 5, 2002 -- Metromedia Fiber Network, Inc. (MFN) (Nasdaq: MFNX), a provider of digital communications infrastructure solutions, has successfully transitioned TheMuniCenter's Internet site to an MFN data center and its Site Operations Platform(SOP), a comprehensive Internet infrastructure managed services solution.

The largest, Web-based B2B marketplace for municipal securities made this transition using MFN's SiteMove solution.

TheMuniCenter, owned by a group of investors that includes several of the largest players in the municipal-bond market, including Merrill Lynch & Co., Salomon Smith Barney, and Morgan Stanley, allows broker-dealers and institutional investors to buy and sell municipal bonds online. The company selected MFN to solve the complex problem of switching to a new data center and to work with its internal IT team to create and maintain a world-class Internet presence.

MFN's SOP allows companies to automatically add bandwidth and services as their Internet sites grow. To meet the needs of companies, like TheMuniCenter, that have already invested in building their own Internet infrastructure, MFN's SOP can be tailored to include existing hardware while still offering a 100 percent Service Level Agreement (SLA). Alternatively, SOP can be a complete outsourced solution by providing hardware, software, co-location, bandwidth and ongoing management and services.

In moving from its previous data center provider, TheMuniCenter implemented MFN's SiteMove solution, eliminating site downtime, equipment loss and resource allocation. Each step of the SiteMove service is designed to maximize efficiency and minimize risk. By providing everything required to migrate its Internet site quickly, reliably and without interruption, MFN enabled TheMuniCenter to focus on its core business, which is Internet-based trading of fixed income securities.
