A PlayStation Network outage that started on February 7 is the most extensive the service has suffered in a long time, and there might be reason to believe that it's the work of bad actors. Although it's expected that online services will occasionally have interruptions, they're usually fairly brief.
According to a Bluesky post from The Verge senior editor Tom Warren, the extensive service outage could be the result of a DDoS attack. A major DDoS attack targeted Xbox over Christmas, so in the absence of any official answer from Sony, something similar could well be the cause of the PSN troubles.
