Read tweets from Ono apologizing. They weren't expecting this to happen and this isn't what they wanted at all. They aren't sitting back saying "Good to know" they are scrambling to get this fixed.
Have they tried unplugging their router and plugging it back in after a few minutes yet? If not, they should try that and if it doesnt work then try calling their internet provider.
Either way, this Start Screen is working great!
In all honesty, this was meant to test their online functionality. Its been along time since I can remember a online Beta going smoothly day one and its almost expected to happen for MMOs. But for the love of God, please add a training mode asap while we wait for the servers.
