Suddenly can't connect to Playstation Now, website says it's not down...

I'm in Las Vegas, if the area matters. I have no trouble connecting to or using PSN features, connection speed test is fine, even the browser works with no problem. But suddenly when I attempt to connect to PS Now, I get an error that says "Playstation Network is temporarily unavailable. Please try again later." I have had no problems connecting in the past, this just started today. Any suggestions? Is this happening to anyone else?
