I have one website hosted with go daddy and it it dont' work with certain ISP in india. I am not sure what is the reason when i was sitting on one ISP internet connection i tried to ping my site domain and it said Also my server is online for the last 1 year and i have not altered it's name servers in this period So not sure where is the problem any idea ...?
The IP address of your ISP might have blocked in between. Try tracert to your domain and then check where it is getting blocked? Fyi, your website is working fine at my end.
The ISP could be blocking it for some reason (sometimes they block whole IPs instead of just a URL which has a nasty side-effect of blocking any other sites using the same IP) or their routing could be broken. Best to get in touch with them and have it sorted out.
GoDaddy doesn't have this rule written, but I face problems with emails not delivered because they block IPs at their sole discretion.
