why the website request the url "http://ift.tt/2q6ANWh"?

I found my site inexplicable to request such a URL(http://ift.tt/2q6ANWh) through Google chrome's developer tools ,and the request always fail the pic for Google chrome's developer tools

I refresh the webpage 20 times, at least this situation appears 5 times。
