Internet Full of 'Black Holes' [Tech News]

[Admin]

You're pounding the keyboard, double-clicking away, sighing and grumbling, but to no avail: That devilish little hourglass icon refuses to give way to the Web site you're trying to reach. Most Internet users have encountered trouble reaching online destinations, but they often attribute the problem to their wireless network cutting out or a server momentarily going down.
Sometimes, though, the problem is more mysterious. At any given moment, messages throughout the world are lost to cyber black holes, according to new computer science research.

Ethan Katz-Bassett, a graduate student in computer science at the University of Washington, and his advisor, Arvind Krishnamurthy, designed a program to continuously search for these strange internet gaps, when a request to visit a Web site or an outgoing e-mail gets lost along a pathway that was known to be working before. To make sure the black holes they detect are not simply due to a problem with the end user or the host server, they look for computers that can be reached from some, but not all, of the Internet, meaning the issue must be occurring en route.
