The website of the Graduate School of Hubei University crashed due to heavy load. According to the public information about the query, the number of graduate students enrolled in Hubei University was too large, and the server could not handle so many requests in a short time, so it crashed. When thousands of user requests suddenly flood in, the load on the server is limited, and some requests will be discarded. If you continue to add more requests, the server will run at full capacity and a large area will be inaccessible.
