Every once in a while (it doesn’t happen very often) DNS servers would stop resolving certain domains causing intermittent issues when accessing the Internet. To solve the DNS issues, I often switch DNS servers on my main router. Changing DNS servers may require rebooting your router.

So, here’s a list of DNS servers you could use on your router, in case the current DNS servers you are using is having problems. I primarily use OpenDNS and Google DNS servers, but others DNS servers are reliable as well.
