Back at the beginning of 2013 we began rolling out our new Anycast network. As of yesterday, December 27th, we've replaced our Unicast servers with Anycast. All DNSimple customers now have access to our Anycast network at no additional charge.

Here are some common questions you might have about this change, along with their answers.

What do I need to do to enable Anycast?

  • If you were using our Unicast network with our name servers ns1.dnsimple.com through ns4.dnsimple.com, then you do not need to do anything - we've already switched you over to Anycast.
  • If you are using our Anycast network with our name servers ns1a.dnsimple.com through ns4a.dnsimple.com, and your domain is registered with us, then we will be switching your name servers back to ns1.dnsimple.com through ns4.dnsimple.com shortly.
  • If you are using our Anycast network with our name servers ns1a.dnsimple.com through ns4a.dnsimple.com, and your domain is registered with another registrar, then you will need to switch your name servers back to ns1.dnsimple.com through ns4.dnsimple.com at your registrar.
  • If you are using our Unicast network with vanity name servers, and your domain is registered with us, then we will switch you automatically.
  • If you are using our Unicast network with vanity name servers, and your domain is registered with another domain registrar, then you will need to update the IP addresses for your vanity name servers using the addresses in http://support.dnsimple.com/articles/dnsimple-nameservers

If you are required to change your name servers at another registrar, you will need to do so by March 31st, 2014. We will shut down our Unicast network permanently in April. We will also remove the ns1a through ns4a names at that time as well.
