EXO fans crashed the server of ticketing site for EXO's upcoming concert.

The website of YES24, a Korean ticketing agent, crashed within a minute of EXO PLANET #2 - The EXO'luXion's tickets going on sale on January 21. The tickets went on sale at 8PM KST, and the website crashed due to over one million users trying to access the site to buy tickets.

According to the K-Pop Herald, YES24 had to stop the sales.

"To minimize the damage to the audience," said an official. "We could not help but stopping sell the tickets for now and reschedule booking for the concert."

Fans of EXO will be able to purchase tickets for four March shows on January 28 and 28.

EXO PLANET #2 - The EXO'luXion will be held in Seoul in two parts. The first two nights of the show will be held on March 7 and 8 at Seoul's Olympic Gymnastics Arena, and then there will be two more shows there the following week, on March 14 and 15.

These concerts will feature ten members of EXO, following the departure of two members leaving the group in 2014. The group continued to promote throughout 2014 with the remaining members, and won several year-end awards.

SM Entertainment, EXO's representative agency, released a teaser for the concert event.

EXO debuted in 2012, and has become one of K-pop's most popular idol groups.

It is expected that EXO will be releasing new music within the first half of 2015. The group released a teaser video for their comeback, which was initially removed from YouTube due to alleged plaigarism. The situation has been rectified, and the video is now on YouTube.
