1. We're aware that many of you are having problems connecting to PSN, and yes, we're looking into it. Stay tuned for updates.
Feb. 28th 2010 a unknown number of pre 'slim' generation PS3s suffered a 8001050F error and reset their clocks to 12/31/1999. Even PS3 that were not on the network recently suffered this error.
Games with Downloaded Content or using the trophy system were unable to play.
Disabling the internet in the PS3 menu then changing the date manually before loading any games that used DLC or Trophies seemed to avoid this problem.
