Don't know if this was connected but recently when trying to login via the godaddy login page was getting a fraud warning message so I wouldn't login via the normal route, had to go to another url entirely e.g. godaddy.com/manage/dcc etc.. Again not sure why I was getting that message and I assume it was just me.
Got this email from Afternic:
There is a known issue affecting log in system-wide. It is a global issue, and is being worked on, as we speak. I do not have a timeframe for repair, but they are trying to get it fixed as soon as possible. We apologize for the inconvenience this has caused.
