I'm not even able to log in. Just getting a 404 error.
Fortunately I hardly have anything on there.
I also wanted to check if I have some historic coins there, just in case.
I've got for sign in "400 bad request", not 404.
I guess that they are trying to do something, just not careful enough to not break everything around

We'll need patience on this...
Must be a Chinese exchange.
My browser tells me it's Swedish, not Chinese. If it would have been Chinese it would be closed or frozen already.
