Eh?

I don't see a delegation to tulku.nic.ar. anywhere down the delegation
chain.

. says ch nameservers are:

NS.APNIC.NET.           2D IN A         203.37.255.97
DOMREG.NIC.ch.          2D IN A         130.59.1.80
MERAPI.SWITCH.ch.       2D IN A         130.59.211.10
DNS.PRINCETON.EDU.      2D IN A         128.112.129.15
RIP.PSG.COM.            2D IN A         147.28.0.39
TULKU.NIC.AR.           2D IN A         200.16.97.77
CCTLD.TIX.ch.           2D IN A         194.42.48.120

all these nameservers agree that elby.ch nameservers are:

elby.ch.                12H IN NS       ns1.elbyns.de.
elby.ch.                12H IN NS       ns2.elbyns.de.

Both these nameservers return identical data to an 'any' query type.

  See:
  http://www.dnsreport.com/tools/dnsreport.ch?domain=elby.ch

  There is a warning for parent servers:

  Your NS records APPEAR to be:

  ns2.elbyns.de. [62.116.162.15] [TTL=80024]
  ns1.elbyns.de. [62.116.130.76] [TTL=80024]

  NOTE: These records may be inaccurate, since the parent servers
  (tulku.nic.ar.) do not know the NS records for elby.ch (or give a referral
  to other DNS servers)! This may cause other tests not to work properly,
  such as the 'Nameservers on separate class C' test.

  This may or may not be related to your problem.
