MENLO PARK, Calif., March 8 /PRNewswire-FirstCall/ -- Digital Realty Trust, Inc. (NYSE: DLR), an owner and manager of technology-related properties, today announced that WIDE Project (www.wide.ad.jp), the research consortium that operates its own IP backbone and the M-Root Server, has selected Digital Realty Trust's 200 Paul Avenue Internet Gateway & Colocation Facility as a new node on its worldwide network. WIDE Project has also selected 200 Paul Avenue as the home for its new West Coast distance education studio. Digital Realty Trust's 200 Paul Avenue is one of the premier Internet Gateways & Colocation Facilities for network providers and enterprises in northern California.

The 200 Paul Avenue Studio will facilitate distance education between San Francisco and classrooms around the world using DVTS high-definition video and advanced data technologies. Using the 200 Paul Avenue Studio, professors from overseas who are traveling in the U.S. will be able to continue teaching students at their home universities, and American professors will be able to conduct virtual lectures to students and faculty at universities abroad.

The 200 Paul Avenue Studio is WIDE Project's first 24/7 distance education studio in the United States, and is a milestone in WIDE Project's efforts to facilitate distance education and educational exchange between educational institutions in countries along the Pacific Rim and across the globe.

"200 Paul Avenue is the ideal site for this kind of distance education studio because of the availability of fiber, Internet transit and peering services, which provide the infrastructure necessary to support the advanced video and data technologies used in the studio," said Dr. Akira Kato, Board Member of WIDE Project and Associate Professor at the University of Tokyo. "WIDE Project is very pleased to be working with Digital Realty to accommodate our global infrastructure and distance education studio."
