A spat between network provider Level 3 Communications and Cogent, an ISP, has left customers of both companies unable to communicate with each other, according to a story in The Wall Street Journal. The Journal reports that subscribers to Time Warner, which contracts with Level 3, have been unable to access commentator Matt Drudge’s Web site,, which is hosted by Cogent. According to Level 3 officials, the dispute stems from an agreement the two companies have to host Internet traffic for each other at no charge, a practice called peering.
