It's better to use dig (package bind9-dnsutils) to first eliminate problems on other DNS. Give us: dig @13.107.206.240 trafficmanager.net SOA dig @13.107.206.240 outlook.ha.office365.com IN dig @172.16.128.40 vijl.staf.tio.nl AAAA dig @172.16.128.10 vijl.staf.tio.nl AAAA > Apr 28 12:07:53 linbobo named[546]: DNS format error from 172.16.128.40#53 > resolving staf.tio.nl/AAAA for client 172.16.17.11#65033: Name tio.nl (SOA) > not subdomain of zone staf.tio.nl -- invalid response I suppose you reboot after your upgrade ? Do you have defined somewhere on linbobo a zone staf.tio.nl ? I guess not but do a grep just to be sure.
