That's a lot of coins and yes they're indeed offline i'm getting the same message from cloudflare including the retry for a live version beside it . Just wait it out i'm sure they're aware about their site being down and doing what they can to fix problem.
when i am trying to log in they are either way giving no page found or a pop up, wrong password or username, when i am trying to click on forgot password to reset it , the page is not opening.
