It means we have an emergency backup system
But why did this happen for a long time?
Kakao claimed it was because the accident was too big 
But Naver, which uses the same data center, was different
Some services such as shopping live were suspended, but there was no large-scale blackout like Kakao for a long time
Naver says it’s thanks to its redundant and backup of major services
Kakao said there are four data centers in addition to Pangyo, where the fire broke out, including Anyang, and Pangyo was the main center, which was severely damaged
But they didn’t disclose how much data they backed up in which data center
He only repeated the claim that the fire was a special situation 
10 years ago, in April 2012, Kakao went down for four hours due to power problems in the data center
At the time, Kakao said it would make a lot of money and distribute its super-powerful data centers across continents
