Games : Tiny Towers store not working?

Why is the store on tiny towers unavailable? And is there anyway to get it to work again? Any time I have tried to go on the store in the past two days it keeps telling me that the store is unavailable and will not connect to the server at all, there for there is no Way for me to earn and bux and I am not able to buy and new bitzens. To be able to excel in the game any further. I am getting very frustrated
