Some of you may already know this, but I thought I would post it here for those that do not.
Sonly will be performing routine maintenance of the PSN beginning the morning of Monday, April 15th. It will start at around 8:00AM PST (10:00AM CST/ 11:00 AM EST) and last until around 8:00PM PST (10:00PM CST/11:00PM EST).
If you attempt to sign-in to the PlayStation network during this timeframe, you may receive a maintenance notification. The PlayStation Store, PlayStation Home and Account Management will not be available during the maintenance period. However, you WILL be able to access online play and applications as long as you have signed into PSN at some point between now and when the maintenance begins.
