"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."
