Off topic:Server not found, Firefox can't find the server www.ncbi.nlm.nih.gov.

Question

[lessismore]

Hey all,

I have a big problem since yesterday. Without any evident reason my computer doesn't connect to NCBI www.ncbi.nlm.nih.gov) no more. No pop-ups opening, i am using firefox and i have tried also other browsers such as Ubuntu browser and Opera. In my same network other computers can access to it. No solution for the moment. NCBI is the only website i could not connect.

Could somebody tell me the reason? Thank you so much in advance
