HAMILTON, Bermuda--(BUSINESS WIRE)--May 25, 2000

Global Crossing Ltd. (Nasdaq:GBLX):

  -- Global Crossing Network is lit and operational from Tokyo to
     Berlin.

  -- Announced global network, to be completed by mid-2001, is on
     schedule and under contract to a diverse group of suppliers,
     including Alcatel, Bestel, Global Marine Systems, ImpSat,
     KDD/SCS, Lucent, Nortel and Tyco Submarine Systems.

  -- "This is the world's first truly global, fully integrated, fiber
     optic telecommunications network," says CEO Leo Hindery, "one of
     the most remarkable, privately funded infrastructure projects of
     our time."

Global Crossing Ltd. (Nasdaq: GBLX), which is building and offering services over the world's most extensive global IP-based fiber optic network, yesterday lit the Eastern Ring of its Pan European Crossing network (PEC), connecting six additional German cities and expanding the reach of its global network to more than 40 major commercial centers in Europe.

Global Crossing confirmed that it expects to complete, on time and on budget, all of the announced segments of its worldwide network by mid-2001. The company also confirmed that all of its announced systems still under construction are under contract to a diverse group of major suppliers, including Alcatel, Bestel, Global Marine Systems, ImpSat, KDD/SCS, Lucent, Nortel and Tyco. (On Monday, Global Crossing filed a lawsuit against Tyco Submarine Systems alleging tortious conduct and breach of contractual obligations. Of the construction remaining to complete the announced segments of the Global Crossing Network, Tyco is responsible for slightly more than five percent.)

The new Eastern Ring is an extension of the high-capacity PEC network and comprises the six cities of Berlin, Dresden, Leipzig, Munich, Nuremberg and Stuttgart. Thirteen other cities in Europe were brought on line in December 1999, when the first three rings of the PEC network went live. The PEC network links major European cities with one another and with the rest of the Global Crossing Network, serving the Americas and Asia.

"The lighting of this new ring in Europe is another significant milestone in the approaching completion of our network construction," said Leo Hindery, Jr., Chief Executive Officer of Global Crossing. "By mid-2001, a bit more than a year from now, Global Crossing will complete the world's first truly global, fully integrated, fiber optic telecommunications network -- one of the most remarkable, privately-funded infrastructure projects of our time. Today, we can carry traffic on our own fiber from 19 cities in Europe, across two oceans and North America, to Tokyo. Three-quarters of this network is being newly constructed and the other one-quarter is new network that we acquired. The rest of the system remains on schedule, on budget, and under contract. This puts us in a position to have a unique worldwide network that will be first in reach, first in speed and first in its advanced technologies."

Added Hindery: "From telehouse locations and Web hosting centers in the world's major cities, the Global Crossing Network will provide unprecedented connectivity to Europe, North and South America and Asia. The value of the Global Crossing Network is its ability to seamlessly link the world's major business centers with nearly limitless bandwidth, providing the world-class tools and services customers need to move information quickly, efficiently and effortlessly."
