A message on the Official PlayStation Blog warns PlayStation Network users that the service will shut down for 14 hours for some routine maintenance. You will not be able to sign in to PlayStation Network during that time, and any websites related to it will also go off the grid until the service returns on Friday. Sony did not disclose what it would be changing or if a new update would be applied during this service outage. From the blog:
"PlayStation Network will undergo a significant maintenance period on Thursday, March 1st. Maintenance is expected to start at just after 8:00 am Pacific and will last for several hours, until approximately 10pm Pacific. Unlike typical maintenance events, consumers who are already signed-in to PSN will be signed-out, and consumers will be unable to sign in for the duration of the maintenance window. During this time, users won’t be able to access the PlayStation Store, PlayStation Home, Account Management or play online.
PSN enabled websites will not be able to service users, including this one. Please stay tuned to the PlayStation Twitter feed for a notice when PSN is fully back online.
We apologize for any inconvenience this may cause."
Plan your day accordingly, because you won't be playing any online PS3, PSP, or PS Vita games for awhile.
