COVID-19 Vaccination Appointment System Capture

[Asia Economy Reporter Kim Ji-hee] On the 20th at 8 PM, the pre-registration for COVID-19 vaccination for the 50-52 age group began, but the reservation site once again went down. This is the fourth time that long wait times have occurred immediately after the reservation opening due to a surge in users trying to book for people in their 50s.

According to the COVID-19 vaccination pre-registration system on the 20th, the reservation that started at 8 PM did not proceed smoothly. After 8:10 PM, a message appeared stating "There are about 80,000 people waiting ahead" along with an estimated wait time of over 11 hours. As time passed, the number of people waiting increased, reaching 180,000 by around 8:50 PM. However, unlike the previous day, there was no sign of the server crashing so far.

This is the fourth time such a site outage has occurred during the pre-registration process for people in their 50s. The site access was also not smooth during the reservations for the 55-59 age group on the 12th, the additional reservations for 55-59 on the 14th, and the 53-54 age group reservation the day before.

Meanwhile, the Korea Disease Control and Prevention Agency (KDCA) temporarily suspended reservations for about two hours until 10 PM after connection issues appeared during the pre-registration for the 53-54 age group that started at 8 PM the previous day, and added six more cloud servers in addition to the existing four to improve the system.

Jung Woo-jin, head of the COVID-19 Vaccination Response Task Force’s system management team, said at a briefing that day, "The estimated capacity for simultaneous connections on the pre-registration site is about 300,000 people," and added, "Yesterday (the 19th), it seemed to be handling simultaneous processing for about 6 million people" after the cloud server expansion.
