Buy a $5/month VPS from Linode, Digital Ocean, or whatever.<br>

The reason for the "two servers" is a valid one.<br>

<br>
because of <a href="https://www.iana.org/help/nameserver-requirements" rel="noreferrer" target="_blank">https://www.iana.org/help/name<wbr>server-requirements</a> and he should not have allowed this setup at all because "Minimum number of name servers - There must be at least two NS records listed in a delegation, and the hosts must not resolve to the same IP address"<br>
<br>
and the next paragraph makes it clear that even a second machine in the same subnet is not enough for obvious reasons<br>
<br>
Network diversity<br>
The name servers must be in at least two topologically separate networks. A network is defined as an origin autonomous system in the BGP routing table. The requirement is assessed through inspection of views of the BGP routing table<br>

<br>
then you can't host your own DNS severS - it's that easy<br>

Regardless this system has worked well since 2002. Only as of 3 NOV 2017 has it started failing<br>
