have have been troubled with my BSNL Dataone connection. I was not able to access some websites, (even Google.com, amazon.com intermittently. I called up BSNL hotline at 1957. The support staff did not have any idea of what is going on. He was aware of some problems with the DNS Servers and did not have any other details.
Finally, I reconfigured my wireless modem to use DNS Servers provided by OpenDNS and now I can reach all sites. Instead of using BSNL (or your ISP’s DNS Servers), configure your computer or modem to use the OpenDNS servers and boost performance and reliability. OpenDNS has provided detailed instructions for the switch over.
