I just deposited cash into a National Bitcoin ATM and its been around an hour and I have yet to receive the requested bitcoin in my online blockchain wallet. Usually this process is instant. Should I be worried or do these things just sometimes take time?

Edit: My online wallet (blockchain.info) seems to be down, if it was down at the time I sent the btc to it, would the bitcoin be recieved once the wallet is back up? Or am I screwed?
