CEO Jay Adelson announced in 2010 that the site would undergo an extensive overhaul. In an interview with "Wired" magazine, Adelson stated that "Every single thing has changed" and that "the entire website has been rewritten." The company switched from MySQL to Cassandra, a distributed database system; in a blog post, VP Engineering John Quinn described the move as "bold". Adelson summed up the new Digg by saying, "We've got a new backend, a new infrastructure layer, a new services layer, new machines—everything."
