Tomorrow, the PlayStation Plus servers go to offline mode, because the Sony will do maintence. They wanted that process work to be done yesterday, but Sony delayed, because the Lizard Squad attacked the PlayStation Plus servers on Sunday.
The maintence start at 9:40 AM, and finish 16:50 PM Pacific Time. Offline gaming will be fine, but the PlayStation 3, and PlayStation 4 owners can not connect to the online services. Team Sony will install the improvements of the back -end network. They need maximum seven hours to refresh the system.
