Interdictor is the name of a LiveJournal blog that documented the effects of Hurricane Katrina in New Orleans during and following the destruction. It is operated by Michael Barnett. At the time he was an employee of Directnic.com, an internet services company on the 10th and 11th floors of an office building in downtown New Orleans at 650 Poydras Avenue, which he referred to as "Outpost Crystal" (after Barnett's fiancée, Crystal Coleman). Daniel Gifford, another employee of directNIC.com, also contributed many articles to the blog. In the early aftermath of the hurricane and flooding, it was one of the few reliable communications links between downtown New Orleans and the rest of the world.
