Renesys Corporation Measures Impact of Hengchun Earthquakes On the Indian Internet Transit Markets

Market Intelligence Services Reveal Massive Traffic Shifts in Quake-Damaged Region

Manchester, NH March 19, 2007 — Renesys^® Corporation, a leading provider of next-generation, award-winning Internet intelligence solutions, today released the latest in a series of reports that compare carriers worldwide. This report provides a detailed look at how North American, European, and Asian carriers fared in the Indian backbone transit market in the weeks following the December 26^th Hengchun earthquake in Taiwan.

By correlating Internet data from a vast number of diverse global sources, Renesys is able to develop a consensus view of the impact of any event, including natural disasters, on Internet routing. Renesys can distinguish purely local effects, such as the loss of individual networks in a region, from more global effects, such as the loss of an entire path or set of paths. Renesys tools help carriers and enterprises audit their Internet transit providers and assess their exposure to Internet outages and instabilities.

“India wasn’t the first place you’d expect to see serious impacts from an earthquake in the Luzon Strait,” said James Cowie, chief technology officer, Renesys. “We were surprised to see how far-reaching the problems were.”

India’s connectivity to the global Internet relies nearly exclusively on submarine fiber connectivity to Asia and, to a lesser extent, Europe. In the wake of the Hengchun, Taiwan earthquake, disruptions to the FLAG and SEA-ME-WE-3 submarine cables caused significant numbers of Indian networks to suffer short-term outages and longer-term instability. For a brief time after the aftershock, more than 10% of all Indian-originated networks were unreachable from the broader Internet.

Even after routes had stabilized several days later, the routes that survived had severe congestion. Paths to Asia, and to the United States through Asia, became unusable or were torn down. Paths to Europe through undamaged cable segments became much sought-after, resulting in secondary congestion on previously unaffected networks.

“The quake should serve as a wakeup call for companies with significant BPO investment in India to step up their demands for redundancy,” Cowie said. “If you depend on the Internet for critical communications, you need to be diligent in selecting Internet transit providers that are making the kind of investment in diverse infrastructure and redundant transit that make a regionally isolating event survivable.”

Renesys Internet Index

Renesys gathers information from the Internet’s routing tables to create an Internet Index for each country in the world, and for the planet as a whole, identifying and ranking major Internet transit providers. The statistics are further broken down into retail (direct to enterprise), wholesale, and backbone (global carrier) indices, to illuminate regional differences in competition and route selection.

Below are the Indian Backbone Provider Rankings surrounding the Hengchun earthquakes, as determined by Renesys Market Intelligence. Backbone provider rankings measure the market penetration of the carriers that provide transit to wholesale service providers in a given geographic market. Significant changes in the Indian backbone rankings indicate broad shifts in traffic as local providers sought to route around fiber paths lost during the earthquake.
