DNS fails during CI

So one of the pre-configured nameservers from the buster cosmos image (195.190.28.82
) fails.
What is this server ?
The authorative nameservers for openappstack.net
are:
;; AUTHORITY SECTION:
openappstack.net. 30 IN NS ns1.greenhost.nl.
openappstack.net. 30 IN NS ns3.greenhost.nl.
openappstack.net. 30 IN NS ns2.greenhost.net.
When I query those I notice that ns1.greenhost.nl
fails to resolve:
root@master:~# dig +short chat.master.ci.openappstack.net @ns1.greenhost.nl
root@master:~# dig +short chat.master.ci.openappstack.net @ns2.greenhost.net
master.ci.openappstack.net.
37.218.246.212
root@master:~# dig +short chat.master.ci.openappstack.net @ns3.greenhost.nl
master.ci.openappstack.net.
37.218.246.212
But not of the authorative nameservers match the IP configured at /etc/resolv.conf
:
root@master:~# dig +short ns1.greenhost.nl
195.190.28.90
root@master:~# dig +short ns2.greenhost.net
37.218.240.208
