It's sad if they really encounter serious financial troubles as some people above are assuming, because it was one of the very few casinos active on the forum. I hope it's just a temporary issue and they will be back in business very soon.
Let's hope it is indeed a maintenance issue but having the issue for week is worrying.
But it's hard not to worry because there are so many red flags.
Sometimes the main provider can create trouble and, in that case, finding a new provider and settle everything takes time. There could be issue with payment services. too.
