I was pretty happy with Google DNS; but since last several hours I'm facing strange issues. The pages load up slower or they just don't load at all. I switched my DNS to OpenDNS and it was good for some time. I spoke with the ISP folks and they say few of the customers are indeed facing issues and the possible resolution is to update your DNS settings to the official DNS provided by DNS. BSNL's DNS works fine; but Google was much faster. Curious to know if I'm the only one or we've more people who've been facing similar issues. Waiting for your responses.
