The message that I got from Shopify:
"Our new servers will make your store faster, more reliable, and more secure. Upgrade today

Hi Victoria,
As we announced before the holidays, we’ve invested in more powerful and robust servers to host all Shopify stores.
These new servers will make your store faster, more reliable, and more secure.
You’ll need to make a small update to your domain’s settings before May 31st so that your store works with our new
servers. This is because your custom domain was set up through a third-party domain provider. The change will take
effect immediately, and won't lead to any downtime for your store.
It’s easy to update to your domain. You can either:
Contact your third-party domain provider and have them assist you in changing your A Record to point to our new IP
address: 23.227.38.32
or
Make the change to your domain’s IP address yourself by following the steps in our detailed guide.
Remember, you have to make this change before May 31st, or your custom domain will no longer work with your Shopify
store. If you have any questions, you can contact us at support@shopify.com."
