From 00:00 on the 12th to today (12th), Moderna vaccination reservations for over 3.5 million people between the ages of 55 and 59 began, and the vaccine reservation site was paralyzed, causing inconvenience to users.



The vaccine reservation site of the Korea Centers for Disease Control and Prevention (KCDC) started at 0 o'clock today, and the server went down due to a crowd of visitors.



It is estimated that at one time more than 200,000 applicants connected simultaneously, resulting in server overload.



When applicants tried to access the site, a message appeared along with a waiting list for access, saying, 'You have to wait for several dozen hours', and in some cases, you could not access the site at all.



The COVID-19 Vaccination Response Promotion Team announced that it will apply for vaccination to 3,524,000 people between the ages of 55 and 59 within six days from today.
