I would like to modify the DNS zone of one of my domains for which Anycast is enabled, but I can’t manage it.
A message says that "This DNS zone is not authoritative for your domain name".
I feel it’s a conflict between OVH’s standard DNS servers and the Anycast ones that are both activated at the same time. I tried disabling Anycast, but that can apparently only take effect at the end of the subscription (February). I also considered removing the DNS servers to keep only the Anycast ones, but they are automatically reinstated by OVH.
The servers dns11.ovh.net and ns11.ovh.net also respond for your domain. But according to the SOA, it is indeed dns200.anycast.me that is responsible for your DNS zone.
The DNS zones between these servers are properly synchronized according to the serial number, and this serial number does not follow the standard numbering adopted by OVH (2080845428 instead of a date).
Are you sure you have the Admin role for the "DNS Zone" part in "contact management"?
If their robot seems lost, I suggest temporarily setting custom DNS to dns200.anycast.me and ns200.anycast.me, waiting for the robot to pass and hoping it doesn’t wipe the anycast DNS zones, then reinstating the official anycast DNS. Otherwise, open a ticket with OVH so they can give the robot a solid kick.
