Guizhou CDC server is abnormal.

The main reason for the anomaly is the underestimation of the short-term super-large concurrency. On September 4, 2022, Guizhou replied: From noon to night on September 3, there was an abnormal situation in the nucleic acid detection system in Guizhou Province, which led to a slow detection progress. After careful investigation, the main reason for the problem is the underestimation of the short-term super-large concurrency. On the 3rd 12, there was an instantaneous huge concurrent visit, and the system could not meet the sudden huge visit, which led to the delay of the nucleic acid detection and collection system and the slow login of large-scale users.
