The Playstation online network is down today possibly tomorrow as well. Here's what the official Playstation blog had to say "While we are investigating the cause of the Network outage, we wanted to alert you that it may be a full day or two before we’re able to get the service completely back up and running. Thank you very much for your patience while we work to resolve this matter. Please stay tuned to this space for more details, and we’ll update you again as soon as we can." I also made a video regarding the issue.
