"Despite its robust appearance, more than 10 percent of the internet flickers out like a candle every day, according to researchers who unveiled on Wednesday an experimental tool that probes the network's dark places.

Ethan Katz-Bassett, a computer science Ph.D. candidate from the University of Washington introduced Hubble -- a network of deep cyberspace probes scattered around the internet - at the meeting of the North American Network Operator's Group in Bellevue, Washington. For two weeks Hubble queried a sample of 1,500 internet prefixes (a small subsection of the net) every 15 minutes. In the end it found that 10 percent of those prefixes couldn't be reached from certain corners of the internet."
