Page "ECHELON" Paragraph 16

One method of interception is to place equipment at locations where fiber optic communications are switched.

For the Internet, much of the switching occurs at relatively few sites.

There have been reports of one such intercept site, Room 641A, in the United States.

In the past much Internet traffic was routed through the U. S. and the UK, but this has changed ; for example, in 2000, 95 % of intra-German Internet communications was routed via the DE-CIX Internet exchange point in Frankfurt.

A comprehensive worldwide surveillance network is possible only if clandestine intercept sites are installed in the territory of friendly nations, and / or if local authorities cooperate.

The report to the European Parliament points out that interception of private communications by foreign intelligence services is not necessarily limited to the U. S. or British foreign intelligence services.
