Seems you are using wrong DNS servers.
Google DNS servers are: 220.127.116.11 and 18.104.22.168
Also try some other DNS servers, for example your ISP ones.
22.214.171.124, yes, my mistake.
With my ISP’s servers it was worse.
When I get the chance I’m going to try Dansguardian for content filtering so I can turn the HAVP proxy off.
