Several weeks ago, I changed over to Google’s Public DNS. I changed over because I was getting fed up with my ISP’s (Rogers) delayed and failed responses.
If you ever had to press F5 and refresh a URL in order to reach your destination, then do yourself a favor and change your DNS. I’ve been using it for weeks and I haven’t had any of the issues I was experiencing before.
There are alternatives such as OpenDNS, but I figured that if anyone knows a thing or two about fast internet, it’s Google.
