The PlayStation Network will undergo a scheduled maintenance today, Sony has announced. The maintenance will run from 9:30 am PST to 3:30pm PST. During the maintenance period, PSN users will not be able to access the Sony Entertainment Network Account Management options, browse the PlayStation Store, or jump into PlayStation Home.
If you’ve logged in since January 20th, you should be able to play online across all devices.
Earlier this month, Sony announced PlayStation Now, their service that will deliver legacy PlayStation games across numerous devices. The service will enter a closed beta next week so we would expect this maintenance to have something to do with that. At this moment, we haven’t received word about how Sony will go about choosing users for the beta.
