Queries originate from this server. Map pins show resolver operator regions; anycast networks may answer from a nearby node. Matching answers do not prove complete worldwide propagation.

Why can a check be unavailable?

Some servers block diagnostic traffic, DNS resolvers time out, or public data providers limit requests. An unavailable check is not a successful result. Try again later or compare with another tool.

Where are the checks performed?

Network and DNS requests originate from the server running this site. Propagation compares multiple public resolvers; their marked operator regions are not separate measurement probes. IP location information is approximate.
