no it wasn't anything you did... It has happened to every one of us smaller guys this last 3 days... I have been down too. It has something to do with the blockchain and my guess is the record cold snap did something to with it. I'm certainly no expert, but I do know it wasn't just you. I checked many accounts my size and lower and they were all out.

Its annoying yes, but it just shows me how much I love it here too :)
