DNS01 not responding to recursive DNS requests
Resolved
The DNS01 server problem has been resolved. As this was our first recursive DNS server to be deployed in our network, it had some old legacy configuration that needed updating.

Once updated, it was confirmed to be fully operational.

We have confirmed that the more recently deployed DNS02 and DNS03 servers are unaffected and were all okay.

Apologies for any inconvenience this issue may have caused.
