We thought that Sony was on top of these PlayStation Network outages, but a major DDoS attack seems to have unsettled the firm's good run of form. The service is down again this morning, with the platform holder reporting that engineers are on the case as we type. Offline time has been kept to a minimum of late, so there's a good chance that everything will be back up soon.
In the meantime, though, you may have to make do with playing your games disconnected. It's frustrating, but we'll update you with more information as and when we receive it.
