About the DNS Propagation Checker

Query the same record through multiple independent public DNS resolvers at once to see whether a DNS change has propagated everywhere or is still serving cached data.

Queries run from our global edge network, so you see what a neutral observer on the public internet sees — not what your local network or ISP resolver happens to have cached.
