Sony has announced that PlayStation Network will undergo routine maintenance today, monday. During the downtime, Sony is going to work on deploying a series of back-end improvements to the network.
The maintenance is scheduled to take place from 6:00 PM BST (10:00 AM PDT) to 1:00 AM EST (5:00 PM PDT). Like usual, players that sign in before the maintenance starts will be able to continue playing online, but won't be able to access PlayStation Store, PlayStation Home, and Account Management.
With Driveclub's rocky start, which suffered some server problems, it may be that Sony is improving their network so that situations like these don't happen again. "We thank you for your patience and support and apologize for any inconvenience this may cause," said Sony.
