I agree to you that they're making it look like there's a maintenance but that's the escape goat that they did. It's so long until this thread has been made and there's no single reply from them.
As others stated here, when you just type goosebet.io it will just lead you into an error website. But when you include the https it will redirect you to the site. It's alarming as they remain the site open luring new users that are not aware of the site's current situation.
Are the goosebet legitimate? Do they have ANN thread here? I think post something like this might cause panic to investors or probably possible investors if they have ANN thread or representative they should at least clear it in the forum so their reputation would not be affected.
They are running good until a delay or stuck withdrawal started a month ago.
