Just a quick heads up to let you know that the PlayStation Network will be undergoing maintenance tomorrow, Tuesday the 25th of August. As a result you will be unable to sign in to the PSN between 4:15pm and 9:05pm UK time. We're sorry for the inconvenience - the maintenance is global, so the timing is not something we have control of. If you're already signed in before the maintenance begins, however, you should be able to stay connected to the PSN servers. It is likely that you'll be disconnected and required to sign back in once the PSN comes back up at 9:05pm, though.

That's 8:15 AM-1:05 PM PST here in SoCali.

The PlayStation Network will undergo maintenance tomorrow, August 25th. Maintenance is expected to start at 8am Pacific and could last for several hours. During this time, users won’t be able to access the store or account management, and may encounter some difficulty while signing in to PSN.

Stay tuned to the PlayStation Twitter feed for updates and a notice when the PSN is fully back online.

We apologize for any inconvenience this may cause.
