If you have LittleBigPlanet you most likely are aware of issues with the online part of LBP. Sony informs on their LittleBigPlanet site that the LittleBigPlanet Servers have experienced significant problems throughout the past 24 hours affecting online game play.

Sony is trying to fix the issues and says the service is supposed to be working again shortly. There is no update yet. Comments indicate that the LBP servers still have issues. Apparently Sony is overwhelmed by the number of players connecting to the servers. Something that was of course expected to happen. Let's see how long it will take Sony to fix it.
Via the LittleBigPlanet site. LBP for the Sony PS3 ships officially since yesterday after a delay.
