Hello, I have double checked this and the support team at my registrar has also checked and confirmed that it's done like in the instructions.
This is from the zone file:
forum IN 300 CNAME n2.nabble.com.
But this is what I get on forum.sator.se:
< HTTP/1.1 301 Moved Permanently
< Location:
http://www.nabble.com/I haven't set up this redirect anywhere on my end.
