The PlayStation Network will be down for maintenance for an 11-hour period on Monday, March 4, from 11 a.m. to 10 p.m. ET, Sony announced today.
The downtime, announced on the PlayStation Community forums, can be largely avoided with some careful planning. Anyone who has signed onto the PSN over the past few days can remain logged in during the maintenance, and continue playing games online unabated. However, even folks who remain signed in won't be able to access the PlayStation Store or PlayStation Home.
