Mac from Shopify here! Thanks for reaching out in our Community forums.
I’m sorry to hear this. We were experiencing an interruption on some stores earlier today. Although, I was able to browse your store and can confirm that the two domains provided are fully functional at the moment:
Where are you currently located? Is this domain hosted by a third party? This issue may be related to Cloudfare’s scheduled maintenance. Feel free to check out their status page here to see if your location is being re-routed or is operational. In the meantime, you can set your primary domain as your my.shopify.com URL as this should be fully functional as well.
If the issue still persists, we’ll need to access your account in order to gather more information about the issue. We’d be happy to continue assisting you through live chat, email, or callback. Please visit our Help Center and log in to your account to create a support request.
Feel free to let me know if you have more questions!
