  • IPv6 Issues for Unicast / Telia

    by Tykling @ February 15, 2021

    Since 01:57 CET today February 15th IPv6 has not been working for the Unicast server. This means DNS lookups to the unicast server 2a01:3a0:53:53:: do not work at the moment. IPv4 is working, and the anycast nodes are working. The provider (Telia) has been notified. I will update here when it is resolved - thank you for your patience! :)

  • Bye ns1, hello unicast.censurfridns.dk, new v6 IP

    by Tykling @ February 26, 2017

    Today 89.233.43.71 has been moved to new hardware to improve response times and stability. The server has also been renamed from ns1.uncensoreddns.org to unicast.uncensoreddns.org to better reflect reality. The old "ns1" name signalled some level of being the "first" or "primary" server, which is not true. DNS doesn't even have a concept of pri…

    One of the reasons most people initially like the idea of blocking child abuse images online is very basic: Blocking something bad, equals doing something good. The less bad stuff we can see online, the better. This is a common misconception. There is nothing good about blocking content that should never be online in the first place. The right thi…
