It's no secret that Hurricane Sandy has worked a number on communications infrastructure, but now a time-lapse video created by Renesys gives us a clearer picture of when and where internet outages occurred as the storm made landfall. Green squares on the map above indicate that 99.95 percent of networks in the area are reachable, while red squares denote that more than five percent of networks are down. In Manhattan's case, Renesys estimates that there was only a ten percent failure, which it considers impressive since power was cut to much of the island. Ten percent may not sound like a huge outage, but the firm points out that population density makes it equivalent to taking a country the size of Austria off the grid. As for the 90 percent of networks in the borough that stayed online, they survived thanks to generator power. If you'd like to witness the playback of outages between October 29th and 30th, head past the jump for the video.
