The PlayStation Blog has given us the heads up that PlayStation Network will be taken down for maintenance from 9:30am Pacific to approximately 4:00pm Pacific on Tuesday, June 25. Here's what you need to know:
"The PlayStation Store, PlayStation Home and Account Management will not be available during the maintenance period but you will be able to access online play and apps provided that you have signed in to the Network at some point between now and the time of the maintenance. So please be sure to sign in now if you wish to access the PlayStation Network during Tuesday’s maintenance window."
Additionally, it's worth pointing out that this week's PS Store update will happen tonight due to the unfortunate timing of the maintenance. Be sure to log on later today before it's too late.
