Discount Ninja Outage History

Incident Summary A hotfix deployed on March 3, 2026 at 6:00 PM ET introduced an issue affecting the checkout flow for some new customers. Under certain circumstances, the discount applied at checkout could be removed when a customer entered their email address during checkout. This behavior was related to a change intended to prevent discounts from being applied after a customer signs out of their account. Resolution The issue was identified and corrected on March 4, 2026 at 8:50 AM ET. Current Status The fix has been deployed and checkout behavior has returned to normal. We will continue monitoring to ensure consistent operation.

A performance problem affecting the product data impacted promotions of a subset of merchants using Discount Ninja between 7:35PM CET and 11:25PM CET.

From January 9 to January 13, an intermittent issue in the cache layer of our backend services resulted in reduced performance of the Promotion API for a subset of Discount Ninja merchants. The root cause was identified as a cache node malfunction. We have implemented improvements to the cache layer to increase resilience and ensure stable performance going forward.

We identified the root cause of the performance degradation as a timeout in a background process affecting accounts with a large number of promotions. The issue has been resolved, and system performance is fully restored.

Traffic to the Admin UI of the app has now also been rerouted to AWS. All features of the app are available again as of 5:55 PM EST.

An issue with stale cache caused some products to be associated to incorrect collection data. This results in problems with the application of collection-based promotions. Timeline: The problem was detected on June 5th at 11:30AM CEST. A fix was deployed shortly after. All cache is up to date as of June 5 at 17:30PM CEST.

The incident has been resolved. Unfortunately some stores may experience partial data loss for the period of November 1st until November 15th. Specifically the number of views, add to carts and initiated checkouts may be underreported for some stores. Note that the number of orders and associated revenue is not included in the data set that experienced data loss. Changes have been made to our reporting infrastructure to avoid performance degradation in the future.

An incorrect firewall rule affected promotions between 11:30 CET and 12:30 CET.

The Microsoft Azure Storage issue has been resolved and Discount Ninja services are back online as of approximately 03:00 UTC on 19 Jul 2024.

This incident has been resolved.
