E’ quanto riportato dall’Independent proprio oggi:

Britain runs a secret internet-monitoring station in the Middle East to intercept and process vast quantities of emails, telephone calls and web traffic on behalf of Western intelligence agencies, The Independent has learnt.
The station is able to tap into and extract data from the underwater fibre-optic cables passing through the region.
The information is then processed for intelligence and passed to GCHQ in Cheltenham and shared with the National Security Agency (NSA) in the United States. The Government claims the station is a key element in the West’s “war on terror” and provides a vital “early warning” system for potential attacks around the world.
The Independent is not revealing the precise location of the station but information on its activities was contained in the leaked documents obtained from the NSA by Edward Snowden. The Guardian newspaper’s reporting on these documents in recent months has sparked a dispute with the Government, with GCHQ security experts overseeing the destruction of hard drives containing the data.
The Middle East installation is regarded as particularly valuable by the British and Americans because it can access submarine cables passing through the region. All of the messages and data passed back and forth on the cables is copied into giant computer storage “buffers” and then sifted for data of special interest. […]

Ulteriore conferma della potenza SIGINT dell’intelligence anglosassone:

One of the areas of concern in Whitehall is that details of the Middle East spying base which could identify its location could enter the public domain.
The data-gathering operation is part of a £1bn internet project still being assembled by GCHQ. It is part of the surveillance and monitoring system, code-named “Tempora”, whose wider aim is the global interception of digital communications, such as emails and text messages.
Across three sites, communications – including telephone calls – are tracked both by satellite dishes and by tapping into underwater fibre-optic cables.
Access to Middle East traffic has become critical to both US and UK intelligence agencies post-9/11. The Maryland headquarters of the NSA and the Defence Department in Washington have pushed for greater co-operation and technology sharing between US and UK intelligence agencies.
