I use OpenDNS's servers, it's 100ms delay to their servers but I don't notice any delays whilst browsing.
Here they are:
Primary Server: 208.67.222.222
Secondary Server: 208.67.220.220
OpenDNS also help to protect you against Phising websites and correct mis-spelt domain names for you. They're opening a DNS server in London as well.
