Propagation Studio is part of DNS Studio, a suite of focused, free tools for checking DNS, mail authentication, TLS, SSL and domain trust. Each tool does one job clearly, in plain language, with a Tech mode when you want the raw detail.
How it works
Propagation Studio queries your record from dozens of independent vantage points on our own resolver network and shows you each answer side by side. Where they agree, the change has landed. Where they differ, those locations are still holding a cached copy that will expire on its own.
Private by design
There are no accounts and no advertising trackers. The domain you check is used only to perform the lookup and show you the result. See our Privacy page for details.
The rest of the studio
Looking for something else? Try DNS Studio for records and propagation, DKIM, DMARC and BIMI for mail, or TLS and SSL for certificates. The full list is in the footer.
