Given yesterday’s hiccup with DNSSEC in .DE Peter - Pete - Eckel from sys4 wrote a summary how NTA helped him to work around the problem yesterday. It’s all German and it is an entertaining read:

(In case you like the presentation style: It’s a combination of AsciiDoc, git, ci runners, reveal.js and a CSS which makes it all look like sys4)

deNIC-Incident vom 5. Mai 2026

Its goal is to enable knowledge exchange, coordination of efforts, and of course to collaboratively improve the adoption of modern internet standards like #IPv6, #DNSSEC, #DANE, #DMARC, and #RPKI.

@it_unke @jpmens If you build the platform yourself you probably will use haproxy to gain HA towards the web services and run PostgreSQL in a cluster. If you get a license from NetBox Labs and use their images it will be kubernetes and other software that gives you HA.
@realmurphy better now? We’ve updated the text that describes the plugin.
@realmurphy well maybe you find Pete’s plugins helpful. They are thoroughly written, maintained and support almost any option - even very old or rare DNS resource records. Use them and write your own deployment using ansible or anything to grab the data and provide the output you need. The plugins are open source.
