[dns-operations] .co broken for non-stock queries?

[Paul Wouters]

I noticed that the .co TLD servers seem to not respond to various
queries, eg:

dig +norecurse -t openpgpkey roessner.co. @ns1.cctld.co.
dig +norecurse -t cds roessner.co. @ns1.cctld.co.
dig +norecurse -t uri roessner.co. @ns1.cctld.co.

It oddly enough does return answers for the private use range.

Anyone know of a .co contact to ask what's going on?
