What is the cause of "server did not respond in time" error message?!

[Kross]

Sometimes, when I open a site, the site would load and along the way, it would not complete the loading and would display a message "server did not respond in time".

What could be the cause of this kind of error message when opening a site? Is it from the user side or from the hosting side?

That is usually due to hosting. If you are limited in bandwith but you get a lot of visits, you might frequently experience this

It’s usually a hosting related issue. There’s something wrong with their upstream server that’s causing connectivity problems.

Indeed it is the hosting,some servers are very slow and your site might receive a lot of users burdening the system
