"App Is Unresponsive, So What?" Government Causes Self-Verification Chaos on First Day of Quarantine Pass

On the 13th, a notice about the application of the quarantine pass is posted at a restaurant in downtown Seoul. From this day forward, to use major indoor multi-use facilities such as restaurants, cafes, academies, and libraries, proof of vaccination or a negative COVID-19 test result is required. Violators will be fined, including both business owners and users. Photo by Kim Hyun-min kimhyun81@

[Asia Economy Reporter Seulgina Jo] "I got vaccinated. The QOOV (electronic vaccination certificate) app is not showing up, what should I do?" "Sorry. We have to verify your vaccination status."

On the first day of the COVID-19 vaccine pass enforcement, during lunchtime on the 13th, a much longer line than usual formed at the restaurant area in the IFC Mall, Yeouido, Seoul. Although empty seats were visible inside the restaurants, entry was hardly allowed. Both employees and customers who came for lunch stood at the door, tapping their feet while holding their smartphones. Their faces clearly showed signs of confusion.

This authentication chaos was caused by the QR code electronic verification system, which confirms COVID-19 vaccination status, crashing from the very first day of the vaccine pass enforcement. The smartphone screens in their hands only displayed the message "Failed to load data."

Some visitors complained, saying, "I got vaccinated, so can't I enter using the Safe Call verification?" and "Lunchtime is almost over." However, since vaccination status cannot be confirmed through handwritten logs or Safe Call, employees blocked the entrances and repeatedly apologized, saying, "Sorry, we must verify your vaccination status." This is because if the vaccine pass is not properly checked and violations are found, both users and business owners must pay fines.

From this day forward, a vaccine pass is required to use indoor multi-use facilities such as restaurants, cafes, and academies. If users enter these facilities without a vaccine pass, they face a fine of 100,000 KRW per violation, and facility operators face fines starting at 1.5 million KRW for the first offense.

Jo, a man in his 30s who works in an office, said, "Since we have to pay fines, I couldn't just ask to be let in blindly, and the QOOV app was down, so it was extremely frustrating." He sighed, "After trying to access the QOOV app for a long time, I finally found a photo of my vaccination certificate taken with my smartphone camera and barely got in." Jo wasted about 30 minutes waiting in line in front of the restaurant that day.

Those who managed to verify their vaccination status through photos or text messages were relatively better off. Others waited 20 to 30 minutes and left hungry, or had their dining plans canceled in front of the restaurant. Another office worker in his 30s, Kim, said, "I used the QOOV app well until last week, so I never expected such a crash today." He added, "I had no choice but to cancel the meeting in front of the restaurant because I might end up starving and returning to work."

The system that caused the so-called authentication chaos began to normalize only around 1 p.m. It was confirmed that similar errors occurred not only with QOOV but also with Naver and Kakao's QR code systems, making them difficult to use. It is presumed that the overload was caused by a sudden surge of users during lunchtime.

The government explained, “The issue was a ‘connection overload’ at the KT DS Cloud Center where the QOOV server is located.” The Korea Disease Control and Prevention Agency stated at a briefing that afternoon, "Currently, the QOOV server located at the KT DS Cloud Center is experiencing connection overload, which has caused processing delays. We are currently investigating the cause." They added, "Pre-booking is still operating without special issues, and we are consulting with related agencies to improve the QOOV server's functions." They plan to hold consultations among related agencies and prepare measures to prevent recurrence to restore normal service.

However, criticism continues that despite announcing the expansion of the vaccine pass two weeks ago, the government failed to properly prepare basic server expansions and other measures. It is natural that the number of users would surge once the vaccine pass is mandated. It has been confirmed that there were no operational failures at the KT DS Cloud Center on that day.

The government should have anticipated and prepared for the expected surge in connections, but it is presumed that the scale of the previously implemented server expansion could not keep up with the volume of connections on that day. This is essentially a failure in demand forecasting. A restaurant official located in Yeongdeungpo-gu, Seoul, said, "Even last week around lunchtime, the QOOV app authentication was not working well," and added, "Considering that it would be fully enforced starting today, this was a somewhat predictable situation." This is why public criticism that the government itself, which has repeatedly emphasized the vaccine pass, caused the authentication chaos cannot be ignored.
