ATDS Checkout Throttling Bug – 10-Year Shopify Store – 0 Orders for Hours – No TMS Response (4+ Days) I am a 10-year Shopify merchant and my store has been experiencing a severe recurring checkout failure for the past 3 months.
Orders suddenly stop for 6–12 hours at a time despite confirmed high traffic.
This has happened repeatedly and only resolves when a Shopify support advisor or staff member opens my store admin — indicating an issue with Shopify’s Automated Traffic Defense System (ATDS) or rate-limiting.
