https test shows up as white icon and no alerts

[usa ims]

Hi,
In my hosts.cfg I test 4 web sites by their URL but only two works as expected by turning red and alerting. But the Washington and Illinois does not alert nor turn red -- it indicates a true error by stating 'DNS error' but it turns white or clear and does not alert. Does anybody have a clue? I have masked the URL for security reasons.
