A systems glitch at CNN.com hobbled the Web site of the cable TV news channel for about three hours Monday afternoon, said Keynote Systems. San Mateo, Calif.-based Keynote, which measures how quickly visitors are able to access a Web site, said that CNN's front door could only be downloaded about 46.8 percent during a span from noon to about 3 p.m. PDT. Normally, visitors to CNN.com log on with ease, or about 98 percent of the time, said Dan Todd, Keynote's chief technologist for public service.
The glitch was a result of human error, said Edna Johnson, a CNN spokeswoman. She acknowledged that the malfunction slowed the site but said that it never rendered the site completely inoperable. During one 15-minute period, however, starting at about 1 p.m. PDT, visitors to CNN.com could log on only 13 percent of the time, a very low success rate, Keynote said.
