What do the verdicts mean?
Blocked: a detector proved interference. Redirected: the mainland China probes ended on a server inside the country. Intermittent: probes disagreed, or the address alternates between reachable and blocked. Not blocked: the probes matched the control. Not enough data: the test could not tell. Unresolvable: nothing anywhere resolves the domain, so there is nothing left to block — usually an expired or parked domain.
