Four out of the 13 servers that manage global Internet traffic failed briefly Wednesday night.
The technical glitch was a "nonincident," and no users or Web sites were affected, said Brian O'Shaughnessy, a spokesman at Network Solutions Inc. (NSI) in Herndon, Va. The problem hit for a little under a hour, and was fixed in 30 minutes, he said.
According to NSI, the glitch was found in the Berkeley Internet Name Domain (BIND) software, which connects Internet Protocol addresses to a Web site name, such as eBbay.com. BIND's layers are "glue that connects the domain name servers," he said.
The problem affected four of the world's root servers, which stopped responding to requests for Web sites ending in ".com." Two servers are located in Virginia, one in California and one in Tokyo. When the glitch occurred, all requests rolled over to the nine remaining servers until the problem was fixed, O'Shaughnessy said.
NSI, a Herndon, Va.-based unit of Verisign Inc., is a registrar of Web addresses.
