How do I correct this annoyance??

For the past few days, I get an error.."page cannot be found". At the bottom left of the screen it says 'resolving host"., then I get the 'page cannot be found" error, 

then it will give me the page. This happens in Chrome mostly. I've cleared the cache, & cookies., even uninstalled & reinstalled the browser, restarted the computer, but the situation persists. I find this happens mostly in the mid-late afternoons. I've used IE...same problem. What can I do to resolve this issue?
