<p>
this is my anonymous dns server. you are free to use it, but just letting you know, this is mine, so it only really has features i care about.
</p>
<p>
the only thing i record are long-term metrics, for the health of the service.
</p>
<p>
it's meant to preserve my privacy (along with anyone who is using its).
in large, my goal is to avoid my dns data being sold to advertisers.

the server is in linode ORD datacenter. if i believe that linode one day is unfit to run this service, i will switch.

i'm really lazy, so the truth is, this is made from patching together a bunch of open source tools
