Those of you awash in the flood of unfiltered, uncorroborated news describing how a Chinese ISP hijacked 15% of the Internet may want to read Craig Labovitz's stellar article on the incident. For those of you with children in the room, let me warn you in advance: Craig's article is awash with facts, statistical evidence, and constructive insight.
Here are some teaser facts and insights from Craig's article. First, the facts:
"On April 8th a Chinese Internet provider announced 40,000 routes belonging to other ISPs / enterprises around the world."
"ATLAS data from 80 carriers around the world graphed below shows little statistically significant increase [in traffic forwarded to the Chinese ISP] due to the hijack on April 8, 2010."
Based on observed traffic, the diverted traffic "never topped a handful of Gbps. And in an Internet quickly approaching 80-100Tbps, 1-3 Gbps of traffic is far from 15% (it is much closer to 0.015%)."
[Note: ATLAS is reputed to be the world's largest distributed darknet sensor network. In common language, it's a gigantic monitoring system that collects and analyzes Internet traffic from collection points all over the globe.]
Now the insights:
"in an industry crowded with security marketing and hype, it is important we limit the hyperbole and keep the discussion focused around the legitimate long-term infrastructure security threats and focused on technical realities."
"We need to fix Internet infrastructure security, but we also need to be precise in our analysis of the problems."
