.ch registrar can't find ns3.dreamhost.com

I’ve added ns1, ns2, and ns3 to the nameserver list on the domain registrar’s side. For reference, this is nic.switch.ch.
Here is the output given by the registrar:
The exact error is “Test: [TEST SOA record present]: server failure (IN/SOA: framba.ch.)
==> ns3.dreamhost.com./66.33.216.216”

Disregard this thread. I asked the registrar to re-test the nameservers, and it came out okay.
