I just re-found the news: http://www.computerworld.com/s/article/9197019/Update_Report_sounds_alarm_o= n_China_s_rerouting_of_U.S._Internet_traffic The article I linked above contains 2 incidents: The first incident rerouted traffic for a huge swath of Internet, including traffic destined to Microsoft, the Office of the USA SecDef, and others. The second incident blocked traffic for some sites, notably Twitter, Yahoo, and Facebook. BOTH incidents happened because of BGP poisoning. BOTH incidents affected traffic FROM the USA to destinations IN the USA even though the poisoning happened from OUTSIDE of the USA. The country where both incidents happened (in these cases, China) is not essential. ANY country with a BGP router connected to the backbone can easily poison other international backbone routers. Especially if said country has a HUGE International bandwidth.
