Sony has taken PSN down, supposedly for “maintenance,” and it may stay that way for a few days. However, this does not come on the heels of any announcement or planned features, meaning this was not planned. While it’s all together possible something broke, the European side of PlayStation states the outage is possibly the “target of outside sources.” This comes not long after a planned protest by Anonymous, the internet hacker group that tends to take out their frustrations on specific targets in this way.
On another note, it should be noted that while this is all going on, you cannot play Bionic Commando Rearmed 2 or the Final Fight/Magic Sword combo on the PS3 at all. Those Capcom releases use always on DRM and require authentication. Welcome to the world of digital content.
