What can happen if a large number of people access a Web site at once

If a large number of people access a website at once then it can either slow down drastically or will not allow any person to access the website. This happens because the number of access requests coming to website server is far greater than the server can handle. Although traffic to any website is important, but choosing the right kind of server with the right capacity to handle incoming traffic is also highly important. The server can get totally shut down if it cannot handle the incoming traffic. Big websites with large capacity servers are more likely not to get affected by such problems unless there is an attack by a hacker.

That could result to the website crashing or the server becomes down also can be very slow
