PSA: PSN Under Maintenance Today
Sony is performing some behind-the-scenes updates to the PlayStation Store today. That means you could potentially find online access to the PSN and its various services blocked off until it's completed.
The updates began at about 7 CDT, and will end this evening at 11. Sony says that if you've connected to the PSN over the past few days, there's a possibility that everything will be hunky-dory, unless it isn't.
In other words, if you've got plans that involve the PSN today, use a pencil instead of a pen.
