出于安全事故考虑，HiCA选择在2023年6月6日停止所有服务。所有已签发证书请立即切换到其他CA的产品。由此带来不便我们给所有用户表示深深的抱歉。江湖路远，也许我们会再次见面的。另外有句话给 gzchenjz，请停止 DDoS 行为，所有证据已经固定，如果不停止我们将在周一起诉至法院。 https://hostloc.com/thread-1177834-1-1.html.

Due to security incidents, HiCA stopped all business since June 6th, 2023. All issued certificates shall consider switch to other CAs service. Deeply sorry to all subscribers.
