We’re aware that some of you may be experiencing difficulty accessing the PlayStation Store at this time. We have a dedicated team working on it now and will let you know as soon as things are back to normal for everyone, both here and on the PlayStation Twitter account. We thank you for your patience, and hope to have the Store up for everyone shortly.
UPDATE: The engineers have finished their maintenance, and applying the final tweaks. The Store should be functioning now as normal. Thanks again for your patience.
