Cryptocurrency exchange OKEx CEO Jay Hao posted a Weibo post: "Friendly products and technology are not competitive, but OKEx bought DDoS to attack Kazakhstan. It doesn't matter, OKEx Global Technology Department is on duty 24 hours a day, and completes anti-D traffic switching in minutes. In addition, this large-scale DDoS attack is handled by the alarm. "Then he said:" Although it is only a few minutes, it does cause inconvenience to some users. No matter what the cause, I apologize to everyone. "
