Coupang services experience two-hour outage due to upgrade error

Coupang, Coupang Eats, and Coupang Play experienced a widespread service outage on the night of the 9th. The disruption began around midnight, with users reporting errors on both mobile applications and websites. Many encountered a message stating, “Network connection is not smooth. Please check your connection status and try again.”

By 1:00 AM, while the main Coupang app screen became accessible, users were unable to log in or view specific products. The outage also impacted logistics, as delivery drivers reported being unable to verify completed deliveries through the logistics site.

Services were restored by approximately 2:30 AM. Coupang issued a notice stating that the disruption was a “temporary error that occurred during the service upgrade process” and confirmed that all services had returned to normal. The company is currently investigating the exact cause of the incident.
