Resolved after 49 minutes, affecting Smart Cart, on July 7, 2026.
**Incident Date:** July 7, 2026 **Duration:** Approximately 45 minutes **Status:** Resolved ## Summary On July 7, a routine script update briefly caused Smart Cart to fail to open for a portion of shoppers on some stores. The issue was regional and intermittent rather than a full outage, and normal service was restored within about 45 minutes. ## What Happened During a routine deploy, a small subset of shoppers loaded a mismatched pair of script files depending on their location and timing. This caused the cart to not initialize for them. Once identified, we rolled back the change and confirmed carts were opening normally again. ## Resolution We shipped a safeguard the next day to prevent this specific scenario from affecting shoppers going forward, and we're rolling out a longer-term update to how these files are versioned to close this out completely.
