Mass Effect 2's Cerberus Network is currently down on PS3. Joystiq has an email from EA support saying that the publisher is aware of the problem, and sources at Sony tell us it is working on a fix. There is also this EA support log which states: "The Cerberus Network and comic part of the Cerberus Network is currently down and hope to be up and working in next 24-48 hours."

We've contacted Sony and EA of an official explanation of the situation. Normally we'd guess this is a classic example of the "PSN hasn't updated yet" issue, but at the moment, neither corporation will confirm that.
