The New Albany Gazette has a lengthy article on plans by a group called MEGAPOP to have a high-speed fiber optic link in northern Mississippi, which would have points of presence in Oxford, Tupelo, Columbus, Starkville and Meridian, mostly using an existing unused (or “dark”) link for much of the backbone; most existing commercial links in this part of state go through Jackson (there are some non-commercial Internet2 connections from the University of Mississippi and Mississippi State University, however). The backbone would connect to existing fiber links in Memphis and Meridian to provide high-speed Internet access to the rest of the world.
