Interesting, it seems this script is (sometimes?) picking up the A record which should have
been gone from DNS cache: 

# dig +trace -t a sa-update.dnswl.org <http://sa-update.dnswl.org/>
(…)
sa-update.dnswl.org.    21600   IN      A       116.203.4.105

# dig +trace -t soa dnswl.org <http://dnswl.org/>
dnswl.org.              21600   IN      SOA     zone-ns1.dnswl.org. admins.dnswl.org. 1903112142
3600 1200 302400 21600

„1903112142“ is 2019-03-11 21:42 (in CET), ie three days ago. 

I see that the old IP 78.47.167.123 only appeared every few hours (taken from the Date: headers
in the past few mails):

Is it a DNS issue on sa-vm1, or is it something I overlooked on our end?
