Yeah, we're back up. One of the scheduled maintenance tasks was "stuck" apparently, so I just had to run them all manually and Voila!
Sorry for the inconvenience/delay!
I tried on my laptop, an older machine than the one I'm on now, using 4 different browsers, but none of them could get on. But here I am on ST using my newest computer and Safari, with no problem getting on. I don't understand...
