Not sure to be honest, I use 3 DNS servers..one of them Google DNS, one is a NJ Optimum DNS and the last is OpenDNS. I can connect to Google just fine.
OpenDNS does/did some screwy things with Google and also with names that can not be resolved and the default Google lookup that occurs with some browsers for that Name. Some people object to what they do, others think it is a good idea. So if you are using opendns as your DNS server and for some reason Google did not load for them, I suspect you would see something like that page.
go to OpenDNS Dashboard -> Settings -> Advanced Settings and uncheck "Enable typo correction" under Domain Typos. Apply the changes, wait for five minutes and youll see the standard browser error messages and not the OpenDNS branded search results.
