网站404
404 error is when a website can’t be found on a server. It typically occurs when a user enters a wrong URL, when a page has been removed or relocated, or when a website is temporarily down for maintenance. Typically, when a 404 error page is displayed, it will tell the user that the page they requested cannot be found, and often provides a link back to the home page or other major sections of the website as well as a search field.网站404
