|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.|
|As with Irene last year, we were in the path of this storm. In fact, our data center in Portsmouth, New Hampshire experienced multiple power outages in the last 12 hours. Despite this, our exceptional operations staff have continued delivering our services and products without interruption to our customers around the world.The graphic on the left illustrates the locations of some of the Internet outages we observed in the impacted region at various points in time over the last 30 hours. Notice how New York and New Jersey bore the brunt of the damage as the storm progressed.
|Our Internet Health Portal (IHP) provides detailed reports about the current state of the Internet for any region in world. A screenshot from this tool is pictured on the right, showing outages by county in New York State. Impacted networks are identified by geolocation, organization, and severity, allowing for detailed assessments of natural disasters and, hopefully, more targeted remediation efforts.This blog represents a quick overview of our data around this event. As we continue to examine the impacts of the hurricane and the recovery efforts, we will post additional findings. Stay tuned.|
