In a move reminiscent of what happened on April 1 (twice in one month MS, for shame!), Microsoft has announced that Xbox Live will be down for maintenance. Only this time instead of going down for only three hours, the service is scheduled to be going down for eight hours. According to Major Nelson, everything will be down from 2am to 10am Pacific Time on April 21. That is a Monday, so traffic would likely have been a bit light, but this does mean that those with downloaded content from a previous console will not be able to access their games. Just so long as it's maintenance of the type that prevents any kind of the hitches the service has seen in its recent history, then it should be worth it. Well, at least we're forewarned.
