NEWARK, N.J. - March 24, 2000 - IDT Corporation (NASDAQ: IDTC) today announced the expansion of its data center operations in Miami and Los Angeles into full service facilities, furthering the company's commitment to market leadership in the rapidly emerging carrier hotel and data center businesses. IDT is a leading facilities-based multinational carrier, telephone company and Internet service provider.

The Miami center has been increased from 200 to 12,500 square feet, while the size of the Los Angeles facility has been nearly doubled, from 6,000 to 11,500 square feet. The added capacity of both centers will enable IDT to increase its client base.

"IDT has always been committed to providing services and developing technologies that address the rapidly changing needs of the communications industry," said Howard Jonas, IDT's Chairman and CEO. "Our commitment to building out our data center operations with the expansion of the Miami and Los Angeles facilities are key examples."

Carrier hotels and data centers are facilities where telecommunications carriers, Internet Service Providers and e-commerce companies collocate their equipment, as well as interconnect their switches and networks. In making such space available on a leased basis, IDT supplies a secure, state-of-the-art environment for companies to house their equipment.

IDT also goes beyond what its competitors offer by providing a complete suite of end-to-end business solutions, including round-the-clock management and maintenance, web hosting, voice services and full 24/7 concierge services. In addition, IDT provides customers with direct connectivity to its voice network and Internet backbone, enabling it to offer extremely competitive rates.

"The operational efficiencies that carrier hotels and data centers can provide to telecom and Internet companies are increasingly becoming key drivers of growth and productivity in these sectors," said Jim Courter, President of IDT, "and with the value-added services IDT offers, we are positioned at the forefront of this increasingly critical area of the communications industry."

The expansion of the Miami and Los Angeles centers comes one month after IDT announced the first phase of construction of a flagship carrier hotel and data center of up to 200,000 square feet at the company's international headquarters in Newark, New Jersey. With the opening of the Newark facility expected this summer, IDT will have five full-service data centers in the United States. The company is also in the process of building out its data center operations in Europe, including the expansion of its existing facilities in London, Rotterdam, Frankfurt and Brussels.

IDT is a leading facilities-based multinational carrier that combines its position as an international telecommunications operator with its experience as an Internet Service Provider to provide a broad range of telecommunications services to its wholesale and retail customers worldwide.

Through its own telecommunications backbone and network infrastructure IDT provides its customers with integrated and competitively priced international and domestic long distance, prepaid calling cards, Internet access and Digital Subscriber Line (DSL) service.
