The official Twitter account for PlayStation in the Netherlands (which has been the most active during this entire outage) confirmed to fans that "internal testing" is currently occurring in numerous regions.

Since that bomb-shell, numerous investigations on NeoGAF have concluded in evidence of players participating in online matches of Killzone 3, LittleBigPlanet 2 and SOCOM 4 over the past 24-hours.

While it's only the slightest trickle of hope, anything is better than nothing at this point.
