In the aftermath of Sandy’s landfall in New Jersey, I tried to make the point that the internet did pretty well overall aside from power failures and equipment that was actually flooded. Renesys has now chipped in with actual data on their blog detailing how a half dozen of the top internet backbones handled Sandy behind the scenes.
The verdict? Traffic on the IP backbones of Verizon, Level 3, Hurricane Electric, NTT, and Tata each was seamlessly shifted to alternate routes to avoid New York City for varying periods of time during the height of the storm. None of them actually went down at all and the data kept flowing, offering a silent tribute to the state of modern network engineering in the face of a Hurricane strike on one of the internet’s largest hubs.
Congrats to the network guys out there who made that happen, across the industry! Now if only we could make a power grid that worked so well.
