Sony's online gaming service PlayStation Network is currently experiencing issues across all platforms worldwide, leaving many unable to play or purchase games.
The network service status site for the online service used across PlayStation 4, PlayStation 3 and PS Vita indicates every aspect of the network is down, including "gaming and social", PlayStation Store, PlayStation Now and "account management." Currently the reason for the problem is unknown.
Upon clicking "details" on any of the services experiencing issues, Sony outlines what features will exactly be effected. Clicking for details on "gaming and social" creates a message that states "You may have some difficulty launching games, applications, or online features. Our engineers are working to resolve the issue as soon as possible, and we thank you for your patience." Players may also have difficulty signing in or creating an account, as well as purchasing games via the PlayStation Store.
Though some games can be played offline, numerous titles, like Destiny and The Elder Scrolls Online are online-only multiplayer titles that cannot be accessed without access to the network. For players who were looking to enjoy the day playing games online with friends, it comes as a major downer if Sony can't get the network up and running quickly.
