I can not access [PubMed](http://www.ncbi.nlm.nih.gov/m/pubmed/) or [MEDLINE](http://www.nlm.nih.gov/bsd/pmresources.html) (a top medical research website) in all my browsers (Chrome, Firefox and Internet Explorer) but I can access all other sites. Also I can access this same website in my Android phone and my wife's PC.

In Chrome it shows, `ERR_NAME_NOT_RESOLVED` sometimes, please how do I resolve this?
