Why does my online store display 'We'll be back soon' message?

[gavincarpenter]

I'm a new Shopify Dev and each time I serve my store I get a message saying We'll be Back soon Shopify is temporarily unavailable, please check back in a few minutes. Is there something I can do to solve this?

Thanks
