Anyway, shopify or whatever is not of my concern, i simply see that the website is almost unreachable. Changing the DNS when i want to reach this or this website is simply not a viable solution.
You're correct. We need to track down and solve this problem.
Setting DNS to Google servers is a good practice anyway. You won't need to change back after visiting our store.
i'm at work now, so changing DNS is not possible, and at home my box already point on google DNS.
