I do not know if you have many F5 DNS/GTM that are different versions because of the update if an update of the big3d is needed on the F5 devices that are in a DNS sync group could help but who knows :
- T-Trust
So i think if nameserver that you have only DC, When you upgrade DC, DNS service go down becasue LDNS cannot reach to name server DC
