Targeted lookup
Query a specific record type, compare it across 8 resolvers or check it directly with the authoritative name server.

Which lookup for what?
One resolver shows what a large public resolver is currently returning. Compare shows whether a change has arrived everywhere. Authoritative name server shows the current state at the source, without caching. If the authoritative name server already returns the new value but the resolvers still return the old one, you just need to wait for the time (TTL) to pass.
