News - End-of-Life Roadmap for OpenDNSSEC OpenDNSSEC will reach end of life in two years, October 2027.

OpenDNSSEC will reach End-of-Life in Oct 2027.

Since 2010, it’s been a trusted DNSSEC signer, pioneering automated key management and zone signing. As operational needs evolved, maintenance became complex. Our focus now shifts to Cascade, a modern, efficient successor.

In equal honour to his induction into the Internet Hall of Fame, we have honoured our colleague of many years, Jaap Akkerhuis, by naming our meeting room after him. Jaap’s response was heartwarming, but as modest as he is, he said a broom closet would also be fine.

We need your help! We're making good progress with #XDP support for our #DNS software. However, to properly test it we need access to two metal boxes with 10Gb/s NICs that have XDP driver support, e.g. docs.cilium.io/en/latest/re.... Please contact us if you can help out. 💚
