The claimed ‘hijack’ of Internet traffic by China Telecom has been 
hugely exaggerated in scale and intent, a traffic analysis by Internet 
security company Arbor Networks has concluded.

A blog by Arbor chief scientist Craig Labovitz picks apart the 
speculative claim, attributed to McAfee’s VP of threat research, Dmitri 
Alperovitch (subsequently clarified here), that the unusual routing 
diversion through China Telecom at 4am GMT on 8 April 2010 could have 
amounted to as much as 15 percent of Internet traffic.

According to Labovitz, this appears to have been calculated by comparing 
the 40,000 affected BGP routes to the 340,000 in the routing table as a 
whole, a calculation originally cited by the industry BGPmon website.

Using numbers culled from the Arbor Atlas traffic monitoring system of 
80 global ISPs, however, traffic on that day barely increased beyond 
normal patterns at most it amounted to only a few gigabits per second 
out of an Internet total between 80 and 100 terabits per second.
