Millions of gamers are unable to play online as the Playstation Network remains unavailable. Users are seeing error messages stating the network is "undergoing maintenance" or is "suspended". In a blog post, makers Sony thanked users for their patience but warned the downtime - which has so far lasted more than 20 hours - could continue for "a day or two". Does it has anything to do with what has happened in recept past? I'm sure sony have lots of annoyed/angry customers right now.
