I was working on a site this week and even had access to the FTP. Suddenly, I can't open the site in any browser(i have firewall off and even disabled anti-virus once to chk incase...) and can't even access it thru Filezilla.
I did the 'cmd > ping > sitename' and it goes:
Request timed out.

My client could access it well and when I used my backup internet connection on the same machine, the site started working properly. So what can be the issue and how to solve it? Someone pls help.
