Group INFINITE, who announced the start of their world tour, had servers go down as soon as the Seoul concert ticket reservations began.

Yesterday, INFINITE began selling tickets for their Seoul concert for their 'ONE GREAT STEP' world tour. 

As soon as ticket sales started, the server crashed due to so many users coming in at once. After about an hour of being flooded with users, the tickets for the concert were sold out.

Due to their immense popularity for tickets, their name also ranked number 1 on the search engine real time rankings. They gained attention as they even beat the Korea vs. Iran game on the search engines.

This is their second sold out concert after their 'Second Invasion' concert from last year.

Their agency stated, "We thank everyone for their support for their world tour. We plan to show the fans the group's best performance and live skills."

This will be INFINITE's first world tour and will begin on August 9-10 in Seoul.

After Seoul, they will continue on to Japan, China and other parts of the world.

On the other hand, INFINITE also recently released their first Japan album and is currently doing promotions.
