We accidentally changed the nameserver settings for our example.be.

The changes were rolled back within minutes. So nameservers were set to the previous ones, provided by One.com. After 16 hours, our website still not working. But are worried that the TLD name servers still do not have nameserver records for our domain.

`dig mydomain.be +trace` or `dig example.be NS @a.ns.dns.be` all reply NXDOMAIN and no nameservers are returned for the domain.

Is it normal that after 16 hours of waiting, TLD name servers still have not been updated and there are no records of our domain?

**UPDATE**

Finally, we got a helpful response from our domain registrar. Here is what they told us:

> 
> this should be fixed now there was an error on the propagation in which the propagation has stuck.

> the hostmasters are continually monitoring this unknown error to check if this is a one time error or not

I believe the problem was that our domain registrar did not propagate updated nameservers to the TLD name servers, that are responsible for .be domain names.

In one minute after their response on the support chat, I could run `dig mydomain.be +trace` and see that the changes were propagated.
