Monitoring the DNS Top-Level Domains

Details on this service.

TLD with at least one serious problem (0)

Warning: the monitor just restarted so no domains are flagged as invalid. You have to come back later to see more results(we do not consider a domain invalid at the first failure, we wait for more, because failures are often temporary).

TLD without serious problems (283)

It is possible that they failed a test recently but it may be a transitory situation.

Generic NIC sheet: Why and how monitoring your domain.

Monitoring the nameservers

Details

We use ZoneCheck to test the Top-level domains. See our FAQ if Zonecheck's error messages are not clear enough.

The policy of ZoneCheck is configurable. AFNIC, for instance, uses one policy to allow delegations in .fr. This monitoring tool, which is build on top of ZoneCheck, uses another one (you can also view it as raw XML. If you install ZoneCheck locally, you can design yet another one.

Policies lists the tests to make and wether a failure is regarded as "fatal" or not (some failures are simply warnings). Any input from the community regarding the policy used here is welcome. But keep in mind that there is no consensus in the community regarding all the tests, except the most basic ones.
