Who runs it
.cz is administered by CZ.NIC, and its expiry process is a transparent registry with a documented process.
What happens after expiry
CZ.NIC operates a defined expiry and release process.
The grace period
There is a period after expiry during which the domain can be renewed.
Recovery after that
After that it returns to the available pool.
Worth knowing about .cz
CZ.NIC publishes its zone data and runs a well-documented process, which makes .cz easier to reason about than many country extensions.
What is true of every extension
- The domain stops resolving the moment it expires. Website and email both stop at once, because both depend on the same records.
- Your registrar panel may still show the domain as active while the rest of the internet already treats it as gone.
- Every stage after expiry costs more than renewing did, and the last stage cannot be undone at any price.
Registry policies change. The shape of the process is stable, but confirm exact windows with your registrar before relying on a number.
