According to the IT industry and authorities on the 22nd, the instability of servers and website outages experienced by ten domestic companies, including low-cost carriers (LCCs) and online game companies, caused by a security program distributed by cybersecurity firm CrowdStrike conflicting with MS Windows, were all resolved on the same day.
