Questo è l’ultimo articolo di James Fallows per The Atlantic sulla censura intelligente della rete operata in Cina (“The Great Firewall”). Interessante ed educativo (Geco-Fil, capito?). Questa è l’intervista con l’autore, disponibile solo online. Si scopre che la rete in Cina ha una natura estramemente fragile in quanto dipende da tre (solo tre!) fasci principali di fibre che entrano nel paese da Pechino-area del Nord, Shangai e Guangzhou.

(…) virtually all Internet contact between China and the rest of the world is routed through a very small number of fiber-optic cables that enter the country at one of three points: the Beijing-Qingdao-Tianjin area in the north, where cables come in from Japan; Shanghai on the central coast, where they also come from Japan; and Guangzhou in the south, where they come from Hong Kong. (A few places in China have Internet service via satellite, but that is both expensive and slow. Other lines run across Central Asia to Russia but carry little traffic.) In late 2006, Internet users in China were reminded just how important these choke points are when a seabed earthquake near Taiwan cut some major cables serving the country. It took months before international transmissions to and from most of China regained even their pre-quake speed, such as it was.

La stessa definizione di “Great Firewall” è scorretta. La censura non è sempre visibile ed è attuata in modo intelligente e subdolo. L’articolo per intero è qui, via The Atlantic.
