DNS Propagation Checker
Check how a DNS record looks across multiple public resolvers at once, and see whether your change has propagated everywhere. Queried from Uptimeify's EU servers.
This check works inside your AI agent, too.
You are running by hand what Claude, Cursor or ChatGPT could do for you directly. Uptimeify offers this and 19 more checks as an MCP server: SSL, DNS, email authentication and more, right in your workflow. No account, no API key, on EU infrastructure.
Frequently asked questions about DNS Propagation Checker
When you change a DNS record, the new value does not reach every resolver at once, each caches the old value until its TTL expires, so different resolvers around the world can return different answers for a while. This tool queries the same record against several major public resolvers and tells you whether they all agree yet.
It queries Google, Cloudflare, DNS.SB and OpenDNS from Uptimeify's EU servers; the domain you enter is sent to us only to run the check and is not stored. As an EU-built, EU-hosted provider, Uptimeify keeps this off US infrastructure and clear of US Cloud Act exposure, which matters for agencies handling client data under GDPR.
After a migration or DNS change, propagation is exactly the window where things break silently. Confirm the rollout here, then let Uptimeify watch the domain continuously and alert you within seconds if a record or the service behind it goes wrong.
