|Last month, Wired.com‘s fascinating geological sciences blog, Eruptions, cast doubt on the purported cause of the December 23, 2012 failure of the Georgia-Russia submarine cable. That is, the author of the Eruptions blog post thought it unlikely to have been due to an undersea volcanic eruption. Without weighing in on the likelihood of active volcanoes in the Black Sea, we tweeted about some of the Internet impacts of this incident, although in 140 characters, we could only scratch the surface.|
In our recent posts about Hurricane Sandy, we analyzed the impacts of the super storm on Internet connectivity in the northeastern US.
From locations around the globe as varied as Chile, Sweden and India,
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.
All reports from Louisiana indicate that power outages as a result of Gustav are extensive and ongoing, with over a million customers still without service and with potentially very long waits ahead of them. The extent of the power outages can be seen in regularly updated maps provided by the state. (A comprehensive list of utilities by region does not seem to be available.) We’ve even heard from state officials that the power problems are worse now than they were after Katrina. So it would be natural to assume that the ISPs in the state were similarly impacted, but that is not the case. Internet connectivity is alive and well in Louisiana and the other Gulf states, with all major providers operational, via either conventional or backup power. End users should have connectivity once power is restored to their homes. We’ll review the past three days from an Internet perspective in what follows.
