Usually you can see this error message on the websites hosted with overselling hosting providers. Their servers are always overloaded by a huge number of websites, so that they just stop responding to user's browser requests.

Solutions:

  1. A. Switch to a decent hosting provider like 2by2host.com
  2. B. Move to a fully managed hosting package, like managed shared hosting at 2by2host.com
