The "healthy cloud" system will not open for a while or there will be delay problems. Due to the large number of sampling personnel, the "healthy cloud" nucleic acid detection system once generated a high amount of instant, making it difficult to log in. After the outbreak of the epidemic, the amount of nucleic acid samples continued to rise. In order to ensure the stable operation of the system, when the number of visits reaches a certain value, we implement current limiting measures and gradually adjust them. After verification, the system fault is not a system fault, but a current limiting protection measure. If the system has a large number of visitors, you can save the registration code through screen capture, which is equally effective and can improve the efficiency of on-site verification more effectively.
