Sony Corporation will shut down the PlayStation Network next week for nine hours of maintenance. The system checks are expected to run from 10:30 p.m. EDT on Monday, May 11, to 8 a.m. EDT on Tuesday, May 12.

Online gameplay will still be available for PlayStation users if they sign in to their accounts before the scheduled maintenance begins. PS3 owners need to have recently signed in, and PS4 owners need to sign in within the 24 hours before the maintenance starts.

However, not every service will be available. Video Unlimited, Account Management and the PlayStation Store will experience some outages, according to Sony's service status page.

The PlayStation Network is occassionally taken offline to perform "essential maintenance." That can include updates to services and also performing routine checks on security. 

The network has faced several security breaches recently. For four days in December, the PlayStation network suffered major outages. Hacker activist group Lizard Squad claimed to have attacked the network. In March, multiple PlayStation users reported fradulent purchases made on their accounts that month.
