The site is down after suffering a hardware failure.
The coins in the wallets are safe.
I don't know right now how long it will take to get it back up. I'll post more when I have more information.
Sorry for the inconvenience.
I have moved the coins from the hot wallet to
a new hot wallet the staking address, in case anyone is watching and wondering why the coins just moved.
There's 3186 coins in the hot wallet which staked recently, are currently "maturing", and so are not movable. I'll move those as well once they have matured.
