Tech:DNS

Miraheze's DNS is self-hosted, on three servers (with two of them being dedicated to this task): ns1, ns2 and ns3. [//github.com/gdnsd/gdnsd GDNSD] is the software used for this task, and we chose it because GDNSD is open-source, fast and easy.

Configuration
Our GDNSD configuration can be find at [//github.com/miraheze/dns GitHub], and can be edited by staff with global root access. That doesn't mean though no one can improve our configuration, because everyone is welcome to create pull requests.

config
config is the file that contains GDNSD configuration. There is a stanza in it that can be used to load balance the main traffic to multiple servers (e.g. servers running HAProxy). More information about the available options in this file can be found here.

zones
DNS records (for one domain name) are stored in a zone (https://github.com/miraheze/dns/blob/master/zones/miraheze.org).
