Just a heads up so you don’t freak out when you can’t log into PSN later tomorrow afternoon: the service will be brought down from 4:05pm on Thursday until 2:00am on Friday, BST to apply firmware 3.70. If you wish to play online during the maintenance, please ensure you sign in to PSN before 4:05pm on August 11. What’s it being brought down for? Brenna has you covered through this link. There’s also some information on the EU PS Blog as well.
