More than a decade after the Internet became available for commercial use, other countries and organizations are erecting rivals to it -- raising fears that global interconnectivity will be diminished.
German computer engineers are building an alternative to the Internet to make a political statement. A Dutch company has built one to make money. China has created three suffixes in Chinese characters substituting for .com and the like, resulting in Web sites and email addresses inaccessible to users outside of China. The 22-nation Arab League has begun a similar system using Arabic suffixes.
"The Internet is no longer the kind of thing where only six guys in the world can build it," says Paul Vixie, 42 years old, a key architect of the U.S.-supported Internet. "Now, you can write a couple of checks and get one of your own." To bring attention to the deepening fault lines, Mr. Vixie recently joined the German group's effort.
