Nah, just point your DNS queries to 8.8.8.8 (two times Adolf Hitler's birthday, easy to remember) and you'll be fine. Or, if Google is blocked, use another root server. Or, if all root servers are blocked, use a VPN. Or, if all VPNs are blocked, invent a distributed DNS system that adds .realuk as a new top-level domain.
