Renesys continues to analyze the impacts on Internet connectivity from Hurricane Sandy. Here’s another quick view of the impact on the routing table as Sandy came ashore Monday night. Each square represents the fate of a set of networks geolocated within a common tenth-degree square of the Earth’s surface — at these latitudes, that’s about […]
Yesterday, Hurricane Sandy came ashore pummeling the east coast of the United States with high winds and torrential rains. The super storm caused major power and Internet outages in a region that is home to more than 60 million people. Unsurprisingly, the impacts on Internet connectivity have been severe. For instance, several major data centers in Manhattan lost power or were flooded.
Besides all the local impacts to the United States, New York City also happens to be a major hub of international telecommunications. As a result of outages there, we’ve observed Internet traffic shift away from the city as carriers scramble for alternative paths.
Last night, a pipeline carrying Iranian natural gas to Turkey was damaged by an explosion, halting gas flow, and perhaps surprisingly to some, disrupting Internet connectivity to northern Iran and Iraq. The Turkish government has accused the Kurdistan Workers party (PKK) militant group, who have claimed responsibility for pipeline explosions in the past, of perpetrating the attack.
Internet communications lines are often installed along existing physical routes, such as highways, power lines, rail lines or oil and gas pipelines. Since someone has gone to the trouble of establishing a right of way and clearing a path over hundreds of kilometers, the telecommunications folks often take the opportunity to lay fiber optic cable along the route, if at all possible.
